CarDelMar 

Having made a booking, paid, and given a reference number - together with the promise of finding alternative vehicles, I was surprised to receive a email at 17:01 - 1 minute after they closed saying
"Hello,
We have received your booking request. Thank you! We regret to inform you that it was denied by the local supplier due to unavailibilty of your selected vehicle category for your requested dates. We are happy to be of assistance to you by making a new car hire booking request with another car hire company (subject to availability). For more help with your booking request, please call our customer service hotline +44 203 788 4464. You can reach us Monday - Friday, 8am - 5pm."
This is useless when I arrive in Mallorca before they open and WITHOUT transport.
They had my mobile number but duid nothing to update me on the situation or arrange promised alternative vehicle.
Total crap service PLEASE don't get caught out by these people.
I made the mistake of not reading previous reviews.

First time booking a rental car.
Placed a booking for a lovely weekend in the south of Portugal.
The booking went through quickly with my Visa Electron. Train of thought at this time in the process was "I got this!".

When we got after the booking and entering my payment info - which was accepted - we were informed about the need for a credit card.

To me, it's not acceptable that they allow me to place the booking with a card they know cannot be used when needing to pick up the vehicle.

Tried calling their customer service, only to get reiterated "Nope - Nothing can be done" which frankly made me quite upset.

Not going with these guys ever again and would not recommend it to anyone else.

Good price for the rental but no impressed with the CardelMar customers service. Sent them an email before rental to clarify petrol policy and got completely ignored! Not good! Fortunately rental was smooth!

I entered my card details and the payment was blocked first time. I went about booking my car from another company. I received an email from CarDelMar saying they wont try again unless I call them and change the details. Despite this they tried every day from there on in with my card details and eventually the details went through and they took the payment regardless of me not even getting the car and having already booked with a different company. This was for an entire 30 day booking so they took over £200. I tried calling and emailing with absolutely NO response even till now. I have now asked my bank to go after them. PLEASE DO NOT TRUST THESE PEOPLE THEY ARE ABSOLUTE SCAM!

I wanted to go to Milan and booked a car there. When I arrived the agency gave away the car. I called CarDelMar and complained and they didn't want to do anything. So they told me to go to the agency an to get an official letter stating that the agency gave the car away. (???) Of course, that agency didn't want to do it.

Support from CarDelMar didn't want to do anything. Just trying to avoid any action. I musst say that was the German part of CarDelMar. SO, at the end, I got no car there. I had to take the train to the place I was going. Instead of 1 hour trip by car, it took me 3 hours by the train. And three hours to come back. Plus the whole trouble with customer service from Cardelmar.

Made a reservation for a car with full coverage for a week in Spain. When it came to pick up the car the reservation desk (InterRent) told me that:
1. There is an extra 60 Euro charge for fuel
2. They do not recognize the insurance from CarDelMar, so if I want to have any cover from them at all I have to by cover from them, there (another 100+ Euro)...

I walked away and rented from their competitor. This is a SCAM to get you in the door. Do not reward this kind of business practices - go elsewhere!

Ho prenotato e prepagato per 8 giorni una auto x mio marito che xo ha dimenticato carta di credito e nn ha potuto ritirarla.. colpa nostra ho pensato nn importa persi comunque i primi due giorni io lo avrei dovuto raggiungere il terzo con la carta e pensavo di recuperare almeno gli altri 6 già prepagati e invece. . Perso tutto! Assistenza call center e apertura ticket inutili! Saccenti e poco utili! Sconsiglio completamente io nn lo userò più!!!!

I paid £154 for rent of car. When I came to Greece I did not get my car. When I called to CarDelMar they said they can not help me with that and I have to contact another local company, When I said I need my money back because your service is rubbish and they said I will not get my money back. So I lost my £154 and when I will back to UK I will go to court!

This is the worst service I have ever received from a company. We took out collision damage insurance only to find out that the insurance is not with the actual car rental company, but with Car Del Mar. It has taken 4 months of fighting with them, for them to refund £100 less than the value charge by the rental agency.

They are rude, unhelpful and quite frankly unpleasant to deal with. Do not rent a car with this company, pay more and go somewhere else.

Very Bad and very misleading,
we booked a car from these services for our Italian trip. We booked full insurance thinking that everything is covered for 118€ . But when we got there its was only minimal insurance. And we had to pay Extra 275€ for a full coverage. Not only me but other customers who booked had the same problem who were standing at the counter with us. Some reservations were unknown to the rental service. Stay away, pay a little extra and save yourself a hell lot of trouble...

It also says a charge of 183€ will be charged if the car is returned excessively dirty. What are you doing, going to repaint the car instead of just washing?

Initially 'booked' a car through Car Del Mar but then recieved an email saying that car selected was 'on request' (ie not actually booked after all) and that I would receive an email within '3 working days' to confirm the booking.

Over a week later I had recieved nothing futher so I phoned them. They said the confirmation email had never been sent (but gave no explanation why).

They then asked if I would like another quote - I said they could email me one. But what they actually did was put this through as another booking (not what I had consented to).

So I then entered a repeat of the original situation (an email saying the car was 'on request'.)

I phoned again to cancel ALL bookings. I was told this had been done.

But then around two weeks later - I recieved another email saying car was on request!

Phoned for a third time - asked for everything to be cancelled again. Asked them to send me confirmation of this. They said I would get an email within 5 minutes.

24 hours later - I have not recieved any confirmation of the cancellation.

Overall - a poor user experience. A lot of time wasted and I got a car through a competitor in the end. Seems they have problems at system level.

I will not be using Cal Del Mar again and can not recommend using them.

Avoid This company as simple as that.
Cus they have no clue about what they doing .customer service is terrible and they will drive you mad for sure .lack of honesty .greed for money.and no experience .

I had to pay for the bus from Heathrow to the Holiday Inn M4J4 hotel. I have hired cars several times from other car rental company which subsidised the cost, so I didn't have to pay.

I arrived one hour and thirty minutes earlier than my collection time, I was told I had to pay an extra day to take the car or wait for 1.5 hours... Again the other car rental company didn't have issues with me collecting earlier.

Finally when I got into the car, the language was set to Italian, so I spent 15 minutes trying to figure out how to use the car!

Not impressed!

Short story - 2 hours after I picked up my rental car booked via CarDelMar from Hertz, I was told the contract based on which I took the car, and the zero insurance policy I thought I purchased didn't really exist, because of some system issue/lack of confirmation. The local partner, Hertz (and not some dodgy firm with poor systems) and I were blamed for going ahead with the rental and left to deal with each other directly, all done in a very abrupt, rude and unhelpful way. Some of the issues that led to this:
- very poorly designed system, for an online aggregator. CarDelMar can take 72 hours to confirm a booking, but the website allows you to attempt renting a car for tomorrow, with no warning. By doing so, you basically give them your card details and the option, but not the obligation, to rent a car for you for the next 72 hours. If they haven't confirmed it by your pickup time, tough luck - you might not get a car. And since they haven't rejected your request, and they have your credit card details, you don't have the option of making alternative arrangements, or you might get charged twice.
- customer service hours are 8am-5pm. This is meant to be sufficient in a 24x7 travel business, in jetsetting Europe, in 2016...
- their system seems to miss confirmations from their local partners - in my case, I didn't receive a voucher, but Hertz did have all my booking details in their system, and had confirmed to CarDelMar the availability, at the time of the initial request
- culture of shifting blame to their partners, and pointing fingers, instead of taking responsibility and ensuring the customer gets the service they paid for; no consideration to dangerous situations like leaving a driver uninsured

After taking extra insurance and putting a claim, Cardelmar said they will credit my account within 2 weeks. That was in November 2015!
I have wasted my time phoning them and sending them numerous emails. They are totally incompetent and useless. They claim they tried to make a payment on my credit card but they simply haven't, instead they close my ticket as if the case was closed. They owe me almost Euro300 and my next step is to take them to the European Small Claims Court!

AVOID CARDELMAR AT ALL COST!

I booked a car last minute with cardelmar, receive their confirmation, call their partner to know how to get there from the airport and they told me on phone that they did not have any car available and not to come. CardelMar charge me and it's been two month I am in the process to get reimbursment. Last news, they said that their partner had car available and that I did not show up. They are lyers and can not be truster. They used the fact that most people are not carefull enough with their expense and don't have the time to do reclamation. It's a shame.

Was not happy at all with the final vendor (goldcar) but cardelmar and their insurance service was great

I cancelled a booking two weeks ago because I made a mistake with dates. I then rebooked with the correct dates. I have had no refund for the first booking and four emails querying that have been ignored. Both bookings were said to be with Hertz.

Because I had become suspicious, I asked Hertz to confirm the second booking but Hertz said they had no such booking. I will recover the money through my credit card company's disputes procedure but CarDelMar are a company to avoid like the plague.

Made my booking and received an email saying they would confirm within 72 hours with their local supplier. Instead, they did nothing - when I called them 5 days later they told me that they hadn't been in touch yet. They then did nothing for another 4 days. Unsurprisingly, a week later the car was no longer available!

If you want to make a booking with a car hire company that doesn't know how to hire a car, then this is the one for you!

Overcharged by nearly EUR80 onsite when collected car. Company agreed to repay, sending me a message to send my bank details. As I was away, I didn't reply, only for the company to close the ticket completely and ignore all emails and calls (when anyone bothers to answer).
A pity, because otherwise good rental experience and price let down by terrible after service.
