Pleasant experience turned ugly

On 1 March we hired a car from CT to JHB. We had just gotten engaged that morning and found out our flights had been cancelled. We wanted to celebrate and get home so we hired a car. The gentleman in CT who assisted us was amazing (Pule.) We arrived in JHB late on the Monday and dropped the car off on the Tuesday after we had been given the all clear. Later that day I received an email to state that there was a scratch on the car and I had to fill out an incident report. After replying and saying there was no incident, all communication from Tempest side stopped. I have sent 3 emails requesting feedback to my response. Today they tried to debit my credit card. When I called the call centre, I was informed that the person copied in on my emails was a teamleader, I was then asked to hold and the line cut off. No one called me back. I then received an enormous invoice but still no response to my emails. After checking the documentation I received in CT, it was noted that the car had numerous chips and scratches. It is very unfortunate that such a pleasant experience has turned ugly. Tempest I would like my deposit back or I will never use you again and will inform family and friends to never use you.
