We didn't purchase full insurance, so the damage deposit was 750 EUR, but after returning the car without any damage, we only received 529.17 EUR back, which means they deducted nearly 220 EUR... This is one problem... The second one is that we returned the car with a full tank, but they charged us 25 EUR full-tank fee and did not refund this amount... The most important issue is that they deducted nearly 250 EUR for damage deposit and return fee... Picture 1 is the contract, Picture 2 is the receipt confirming the car was returned in perfect condition, Picture 3 is the refund status for the deposit showing an unjustified deduction of 220 EUR despite no damage, and Picture 4 is the full-charged rental fee for returning the car with a full tank without refunding the 25 EUR
