RentalCars.com

Misleading website, only made aware of extra charges after payment taken company responded to complaint to late for me to cancel booking, claim this is not the case and they never received my email! Company say charges made clear in small print which is a lie the small print says extra charges will be made clear and payable locally the booking did not make it clear, in till payment had been taken. Company response was tough you should have read the small print! STAY AWAY FROM THIS COMPANY CANT BE TRUSTED AND VERY POOR CUSTOMER SERVICE.

I everything works, rentalcars (=traveljigsaw) is good. I a mistake happens they will never really assist you or give any comment what happened.
September 2011 I booked a car for Italy using rentalcars.com. When I arrived with the valid voucher, locauto (the italian company) told me that the never ever received any booking for me. After a long discussion locauto was willing to phone with rentalcars. Then they gave me a car and said that everything is fine. The guy from rentalcars told me that the booking is valid and ok. So I had my car and brought it back. After arriving in Austria I saw that locauto charged me another EURO 270, - (I already prepaied the car for 70 euro). It needed some very long time to found out why: rentalcars gave me absolutely no comment what happened over 2 months (even the tell you that the maximum response time is 28 days!). Later even the employee of rentalcars wrote me, that she never ever get a answer. What a nice company!
In summary: I continued to explain. They always gave me some stupid answer or found a reason why they did not have to comment my questions.
They never told me who made the mistake and WHY the customer hast to pay 4 times more than it was booked and prepared using rentalcars.com.
So the extra 270 euro I have to pay. Pay attention: a valid voucher from rentalcars might not be valid!

I had very bad experience and just can warn to trust the car offered from this provider.
I inquired for a Toyota Avensis or similar which is Hyundai Sonata according to RentalCars homepage. I paid for Avensis (4 week hire) and received a mail with voucher-link for Avensis. When showing the printed Avensis voucher to Europcar at Cape Town I could choose between Honda Civic or Chevrolet Cruze, both - with no doubt - much smaller than Toyota Avensis. Europcar said they never had Avensis and if I request a car with similar space I must pay for upgrade. A matching car will be available in 4 days! After my mail to RentalCars I got the automatic reply to get an answer within 28 days! Thus I called RentalCars. As usual long time waiting, hardly anybody in charge, finally a lady said she will check my case with the result that next day my previous link was faked and showed Chevrolet Cruze now! From my point of view this is very dubious business practices and a falsification of my voucher document.
In case of problems do not trust the so called free international phone number. I was waiting most of the time in “please hold on”. The one phone call finally cost me € 62, 33.
We could not wait for available upgrade thus we traveled 4 weeks with two suitcases on the rear seats because of the small car boot. RentalCars.com spoiled our vacation therefore never again this supplier.
