lack of Integrity on the Part of Avis

My insurance company hired me a vehicle from Avis on the 11th May-19 due to my vehicle being involved in an accident. I received confirmation from my insurance company that I could collect a rental vehicle from Avis car hire located at the Hyatt in Rosebank. I arrived at Hyatt at approximately 11h30, however there was a number of clients awaiting for their hired vehicles. When it got to my turn, the paperwork was done and I was asked if I needed any optional covers, which I declined. I was told that I could fetch the vehicle in the parking below the Hotel, however assuming that the Avis Car hire is opened till late, I went over to Rosebank Shopping Centre. At approximately 12h15 I received a call from Avis informing that they are closed and I haven’t fetched my rental from the ba*****t parking. I immediately ran from Rosebank Shopping Centre to the ba*****t parking to collect my vehicle, however when I got there ,there was no one there to meet me. I then ran up to the Avis office in the hotel, the doors were already closed, the Avis customer relations opened the door and gave me the keys and described the rental vehicle that was booked for me. When I got to the rental vehicle, there was no one from Avis to assist me with a vehicle check, I did one by myself and immediately picked up that there were scratches on the back bumper, front bumper and a scratch on the bonnet. I noted it on the Inspection form, dated and signed it. Avis collected the vehicle on the 20th Jun-19 as my vehicle was ready. I showed the Avis driver that collected car the scratches and the inspection form and had them sign as well. I received an sms on the morning of the 26th Jun-19 informing me that I am liable for the scratches. I immediately called the Avis Call Centre number that was on the Sms and informed the call center operator to inform of the above situation, she informed that she will escalate the matter to the Avis branch manager at the Hyatt. Living in close proximity to Rosebank, I drove to Avis Hyatt to see the manager in person and have this matter resolved and clarified. When I got to Avis at the Hyatt, I met the same customer consultant namely Tsepho and immediately reminded her of the day she called me from the mall to come and collect the vehicle from Avis at the Hyatt, as they close at 12h00 on a Saturday, she remembered me clearly. I’m so disappointed that I’m being held accountable for the existing scratches that was not verified by Avis and I was given the vehicle without anyone verifying the inspection of the vehicle with me on the day of delivery. This does not show integrity on the part of Avis, as explained to Avis today and I further challenged Avis to verify the condition of the vehicle on cctv cameras located in the hotel parking. It’s not about paying for the repair, but being held responsible for something you never did and was there in the first place
