My flight delayed, I called the rentalcars.com liaison office on the ground, they cancelled my reservation immediately as they would be shut by the time of the landing and assured that nothing was charged. I was asked to fill out a form in the end of the original booking for reimbursement, which I did, simply to hear that rentalcars.com was not going to reimburse me on the amount that they NEVER paid to the local liaison agency. That should be illegal and IS WRONG! Never trust a word of what appears on their website + you can reach no one expect some outsourced 'customer care agent' who's been told to say, 'sorry, we cannot to anything, forget your money.'
