Austrian travellers rented a car in Iceland but damaged it by filling it up with diesel oil instead of petrol. Due to this the car rental company charged them 4.000 EUR and said that any excess would be refunded should the damages prove cheaper than that to repair. However, as the Austrian consumers never received the final bill for the repairs they turned to the ECC-Net. ECC-Iceland contacted to car rental company which then promptly sent the final bill. It was also made clear that the car rental company had not taken as extensive measures to repair the car as the manufacturer had recommended so it was clear that the Austrian consumers were not being taken advantage of.
