Freak team! I rented a car and paid in advance. Then I tried to contact the rental office for 5 days to find out if they accept cash for payment.
I made 39 calls to the Serbian office! 39 times, Carl! Nobody answered me. And then one day before the rental, suddenly someone picks up the phone and says that cash is not accepted.
As a result, I have to cancel my booking and lose 50€, my precious time and nerves.
Just a winner for worst customer service. Numbers I called: +381 11 2097 062, +381 11 3676 644. Give me back my money!
