Avoid Goldcar/Rhodium at all costs - and also the car rental broker sites such as AutoEurope who deal with them and do not reveal which company you are booking with until you've already paid and it's too late! I booked a 10-day rental in Nice via AutoEurope at a total cost of £149.98 On collection at 5pm I asked them to change the incorrect return time at rental end from 8.30am to 12.30pm - a 4 hour change. This was duly done on computer at the pick up desk but the sales person omitted to also change the time on the contract, which error I failed to notice. Goldcar blocked an amount of approx £1400 on my credit card as deposit on pick up and failed to release the block until 9 days after the end of the rental, meaning I was unable to use my card for that period. I also did not receive a final invoice. There was no explanation or apology for this despite several emails and telephone calls from UK to France. When they DID finally release the block they also took an amount of £106, again with no explanation or invoice. AutoEurope contacted them on my behalf to be told that this was for late return of the car. I was charged almost 70% of my 10-day rental cost for a perceived 3 1/2 hour "late" return. COME ON! This is downright dishonest, a rip off, a scam I strongly disputed this charge which arose from the incompetence of the Goldcar employee who failed to make the change I had requested on pick up, but am told that I signed the contract and was aware that penalties would be imposed for non-adherence so they will not refund. Nowhere in Goldcar's contract, website, or rental paperwork is there any mention of a late return charge, though had I been beyond my 10-day rental period I would of course have expected to pay a pro rata charge. NOT £30 AN HOUR - especially as the fault lay with them getting the time wrong, not me. Disgusting company. Don't use them - and spread the word!
