rentalcars.com price comparison and apparently booking & payment as well manchester UK Internet

Hi,

 we booked through rentalcars.com a "comparison site" and paid in advance by debit card to rent a car from dollaruae.com . Apparently in Dubai a credit card is a compulsory form of ID even if you have paid and have a passport. Since we didn't have a credit card to hand, we were refused rental and the adviser said the booking has been cancelled and we would get a refund and as proof gave a copy of an email she sent to the head office cancelling the booking. After returning home we checked the booking email and realised that the online company was registered in the UK and that sounded odd so tried contacting them to inform them as well, however none of the numbers on their site worked and we had to send an email instead. And now the 2 companies are insisting that we should have contacted them separately on the day of collection and that rentalcars.com was not aware that our booking had been cancelled - this seems very odd and self serving considering they communicated the information regarding the booking to dollar in the first place and call themselves their partners.

  They are refusing to refund even part of the AED 2000 that they took as advance payment.

  The entire rental agreement has been drafted to scam customers since the contract is so long and technical you would need a lawyer to explain it to you.
