Surprice car rental Belgrade airport, Serbia. I have been charged whole blocked amount (650 Euro) for very tiny scratch on the bumper. There were two guys 1. Velkjo 2. Drago Banduka (THEY ARE NOT GOOD IN ENGLISH). While picking up the car they were very nice and helpful but while returning they were totally different and make you to do the things hurry. I have asked to park the car in front of the departure entrance while returning so that they don't give you enough time to review the damages and make you hurry to wait in the office. At the office the guy Drago told me to give the credit card I have to charge the damage cost from your blocked amount, I asked how much you are going to charge? He said the total amount (650 Euro) I was shocked and asked why this much for the tiny scratch? He said this amount can be refunded by your online car rental booking company (DiscoverCars). I said I don't have any full coverage policy purchased but he said there is an insurance comes by default on your voucher so you can claim it easily by emailing them all the docs and provided me the invoice, rental contract and all. I was in a hurry too to complete my RT-PCR test also I don't have much time decide and airport was very busy during that time so I left their office and I didn't argue with them. But later when i asked Discover Cars they said you can't claim anything unless you have full coverage purchased. I WAS CHEATED. Please stay away from these guys.
