Dodging evidence - worst experience ever

I rented a car from them on a recent trip. I madenit clear to the lady that I was going to Lambertsbaai which was almost 3 hours away. When receiving the behicle there was visible damage and was reported immediately. I then received a report with no recorded damage. Luckily I took photos and reported. Then they give you a message to log faults with an hour to do so, which was not told at desk. So how do uou log faults whilst driving. That not the worst. Car returned full, but had anbit of dirt outside. All good too. No faults was brought to my attention but I reported all damage again. Then gettjng home after the flight, i get a message to say damage was found. I asked for photo. Supp**** but no damage could be seen on photo. I asked for clearer photos and video entrance video showing damage to fully determine if it was me that caused damage. I was denied footsge and no new photos. I also asked for inspectikn reports, which was supp****, with no defects reported but I have photos of existing damage. So how am I guaranteed it is my fault and not somebody else's damage?

This has been in going for almost a week with no resolution other than insistsnce that I damaged the vehicle. I tried calling since Friday with no answer but mails received.
