Poor service and false claims

I had the most terrible service from Europcar Cape International Airport. Firstly the made and incorrect billing and it took almost 7 days to refund this amount (this was above the correct amount I had paid too). when collecting the car I was sent to 3 different parking bays since they were incorrectly allocated. On receipt of the car there was no inspection report. I returned the car on 16th December and was told all is in order. A few hours later I received a message stating there was damage to the car and a claim had been logged. Firstly I was not aware of any damage I may have caused and secondly I was informed all was in order. It was impossible to contact Europcar - I received no response from the whats app channel, email and no phone calls were answered. My email to the claims department still needs to be answered. I eventually managed to make contact with the branch themselves and received the claim report with a photo of the alleged damage. Luckily I had taken time stamped photos on receipt of the car and the "alleged" damage was existing damage to the car. This allowed me to dispute the damage and the claim was reversed. I received my deposit on 7 January - 4 weeks later. The service and response from Europcar was terrible and it was impossible to communicate with them.
