Europcar the worst car rental service

Do not use Europcar South Africa in Rustenburg or OR Thambo airport. They service is very very poor. I rented a car at Europcar Rustenburg. The guy there just mark the noticeable marks. I dropped it off at OR Thambo airport and the lady there inspected the car with me and said all is good and I handed her the keys. Four days later they send me an email saying there is additional damage to the car and Im accountable for that. I rep**** to the mail saying the car was inspected and all was good when I dropped off the car. Another 5 days passed and just got a mail saying Im accountable for the damage. I asked for a photo but I still did not receive anything. They still did not repay my deposito. I tried contact EUROPCAR customer service but as normal for them no reply. So know that if you rent a car from Europcar they will accuse you of damage of the car and you will not receive your deposito back. Please be warned of this unorganized Car rental service
