AVIS SUCKS

I made use of an Avis vehicle that was arranged via my insurance. I returned the vehicle on the 07.12.22 @ 13:20. I received a call from Liesl at Avis where I booked in the car on 07.12.22 about 3.30 and was advised that my car was returned 1 day late and that I will be liable for payment. I then advised her that my insurance cover is for 20 days and I will ask them to extend the term for me. She gave me an hour to sort out the extension and call her back. I called her back the same day and advised the 1 day was added so I don’t have to pay for it. She said she will complete The necessary on her side so that I can get my refund or deposit I paid. The next day she called me to say they have discovered scratches on the car. I told her that’s impossible because : 1. She has checked the car with me on the day of the return 2. She advised when I left that all is in order. I asked her how can she now call me a day later to advise of the scratches if she was with me when we checked the car. She rep**** that she didn’t check properly and the car was in the shadow hence het not noticing. She called me the following day to say that they investigated and the damage did not happen from their side. I again said to her You checked the car with me and did not advise of any damage. She then told me she will send Me pics of the damage . The last time I spoke to her was on the 08.12.22 and till now have not received any feedback or pics. I am now totally surprised and obviously not happy with having to receive this email asking for payment when the Avis staff member did not inform me of damage in my presence upon checking the vehicle with me.
