Trying To Withhold Customers Deposit

Europcar refund for rental agreement ***.

I returned the vehicle to Cape Town international airport on 30/12/2019. Upon returning the vehicle the vehicle was checked and mileage was taken and everything I was told was in order and left. I then received a call 8 hours later from the depot and was told the car door handle on the drivers side suddenly was broken and they have a claim against me and are with holding my deposit . I find this very strange as the gentleman who checked the vehicle opened the same door to read the mileage and there was no problem with the door handle. Therefore I have the following issues: 1. Why was I only told 8 hours after the vehicle was in the depot and not when this was working when I returned the vehicle and was checked in order before you returned this to your depot. To date no one has actually told me what is the issue with the door handle. I have 4 witnesses who can vouch for the door handle being in order. This sounds like a cover up for someone within your organisation who took the car to the depot, so you don't have to pay out the deposit. 2. Why do I have to phone your call centre who make empty promises someone will call me and have no idea what is going on. I am still waiting for the supposed Cape Town manager to contact me. 3. I called Cape Town International Airport and again this was sent to your claims dept to investigate and come back to me to date I am still awaiting a response. 4. Meantime your company has 9000.00 of my money that I am paying interest upon because of a total lack of communication and service this yet is not refunded to my account. 5. Why has no one from your company called me to resolve this issue. Your communication and service stinks.
