Avis appalling

Appalling. I was given something in the office at Cape Town airport to sign on a computer screen. I didn’t have my reading glasses so assumed it was t’s and c’s and signed. Found out later it included the inventory of damage on the car. At no time was I told this and neither had I seen the car which was outside in the parking on the other side of the building. So not sure how legally I could be asked to sign it. When I got to the car there was a white scratch on the right back wheel arch area . No one came to do an inspection with me as normal and there was no one from Avis there to tell so I assumed they knew. Stupid- I should have taken a Photo and gone back in. Apparently they are paperless I have subsequently been told but it would have been great if the office staff had told me there was no inspection and it was on the documentation on the computer so I would have done my own check and photos. When I returned the car, I said to the staff member- yes there was one this time- the mark was there when I collected. She said no it wasn’t and I had to fill out a dispute form. On returning home I received an email from Avis saying the dent( it was now a dent not a scratch and white mark) was new and I would pay for it and the dispute was closed! I then found my email copy of my rental document which documented the damage in exactly the same place so it WAS there when I got the car. I have asked to see the dates of their pictures and the pictures themselves although this still doesn’t rule out damage in the car park before I collected the car. In the meantime while I am disputing this, both the men I am dealing with are off work until Monday and I have received a message from a different department deducting R2790 from my deposit for repairs. This is absolutely unacceptable as I know that the damage was there when I collected the car and was even on their documentation. What would be the odds of me causing further damage in exactly the same place?!?! They have my money and in all likelihood I will not get it back but I am livid and resent being called a **** when all I have been is a bit gullible. Please beware- do NOT sign that document in the office. Make an Avis employee go to the car with you and take your own photos with them. It will cause huge queues but that is their problem. I on the other hand will never use them again. I used them because they were part of my Ebucks rewards. I am informing Ebucks of this poor operational system and appalling service and really hope they take their business elsewhere.
