Unhappy Customer AVIS car rental paarl

My car was in a accident and part of my insurance is that I get a rental vehicle up to 30 days depending if it is manual or automatic. My vehicle went in for repairs on 6 February Avis was supposed to meet me at the Panel beater at 13:00 as this was arranged a day before the time. Subsequently the AVIS gentleman was half an hour late without letting me know he was running late. This caused me to be late for my next appointment. All the documents were signed and I was handed the key to a dirty vehicle. I took the vehicle but actually felt very unhappy. When I took my vehicle in for the repairs they said it would take ten days so the manual vehicle that was booked I wanted to change to a automatic. Avis Paarl and my insurance contacted me and I went to collect a new vehicle at the Paarl branch on the Friday. I called the branch several times to arrange this but there was just no answer when calling. On Friday I fetched the new alternative automatic that my insurance had approved. The gentleman took be briefly around the vehicle to show me that there were no specific scratches. I took the vehicle. The next week Wednesday the Panel beater called me to collect my vehicle. I called Avis and they told me I can leave the vehicle at the Panel beaters and they will collect the following day. The next day I was contacted by AViS to say that there is s scratch under by the bumper where the gentlemen did not show me that there was no scratches. I went to AVIS the afternoon and a gentleman showed me and told him that it was definitely not me and I was not shown under the car that there were no scratches, the gentleman said that the manager would call me. The Manager never called me. The next day I called Avis and another manager spoke to me, she said she is not the same one of Thursday, she confirmed that she will get that Manager to call me. The manager has subsequently not called me to date. Yesterday I saw that my credit card was debited with the amount of the damage, I called Avis and the person said that the manager will call me. Still no call. I am highly upset about what had happened firstly I did not sc**** the car, secondly I was not shown under the car that there was no scratches and thirdly that no one is getting back to me. Last year December I rented a car at AVIS from Cape Town and the experience was totally different. AVIS Paarl I am really disappointed with the level of service and I have still not received a call.
