Avis Car Hire Centurion ****mers

This is in regards to Avis car hire (centurion barloworld branch) my insurance company rented out a car for me there after my accident, the rental car was delivered to my house by the guy named Tshepo, upon arrival Tshepo did the whole contract thing, paid my deposit and we inspected the car (not in depth though) and even said to Tshepo if he’d inspected the car i would trust he would say if anything was wrong, he assured me all was well and trusted him as i was still in shock from previous day accident. The next morning i pickup a chip on the windscreen which is hidden directly under the wiper, no one could have seen this unless they were looking for it, even i understand how he could have also missed it on his inspection, remember i’m just a normal civilian/driver, i don’t inspect cars for a living and should be considered that they are those small chips or dents one can miss when doing inspection which are conveniently hidden like this one. Then i immediately picked up the phone and tried to get through to the branch to notify Tshepo but unfortunately could not get through after almost 30mins on hold as the line gets through or diverted from call centre and not to the branch directly(took a screenshot of this as evidence) because i could sense that i need to start building a case of evidence, also took snaps of the chip as it was starting to stretch out to become a crack. I then decided to physically go to the branch and report this, luckily i found Tshepo, Tshepo acknowledged the chip and told me he would note and that it wont be a problem when i return the car, i trusted him again and to my gullibleness did not insist he gives me a copy of this note or watch him do it instantly while i was there. Few weeks later when i returned the car, Tshepo wasn’t available, the other guy told me to fill in a damage form, i refused and told him i cannot be held accountable for something that i reported, they then said they would speak to Tshepo and let me know the next day. Elias from the branch called to tell me Tshepo denies having spoken to me about that chip or me coming to report it. So now they trying to pin that damage on me, i logged a dispute with customer care, it was reffered to the branch manager, she called me and i explained what happened, she said she’ll investigate and come back to me, she didn’t, i then called customer care to get update only for them to tell me the branch manager also said the same thing Tshepo said that the chip was not there and i should be charged for it. They are trying to pin this on me and its unfair and shady behaviour. Tshepo is very dishonest and shady because he told me when i went back to the branch that car had just arrived from cape town, it was still new so anything could have happened on the way, and again if the check the car history they wont see any record as i was told by Tshepo that i was the 1st client to drive it. I need urgent intervention on this, its a shame what avis centurion are doing by trying to **** their clients into damages they didn’t do. I also have tried to contact their regional manager. Sent him an email but didn’t respond.
