Dishonest company, do not use

Returned the car without any damage and it was accepted as such after being checked. Then the following day I get an email stating they have discovered some damage now and they want to hold me liable for it even if I did not cause it. It got damaged while under the control of EuropCar at the parking garage at OR Tambo as the photos they send me shows the scratches are clearly visible on the front left bumper above the wheel well arch. I would have noticed this on return and so would the person who checked it after handing the car back but there was none. After numerous emails over the last two months to customer service , the claims department and the collections department they refuse to return my deposit. Even the words in my emails get twisted to try and still blame me, when this is pointed out they refuse to reply. Initially they even wanted me to pay for the damage and keep my deposit. EuropCar is clearly not a company to be trusted and it is much better to use other companies even if need to pay double the rental price. I would suggest to anyone who considers using them to stay far away.
