AVIS - Absolute *******

After years of using them, I also got ****med. On a recent trip to Capetown I was upgraded, checked and inspected the vehicle prior to driving off and used the car for 6 days (didn't even use the free km). Before leaving our hotel I did as I always do and fully checked the car before returning it to the airport. When arriving at the airport, we waited until a full inspection was done and I confirmed that there were no issues and all was in order. Including the guy standing in front of the car making all his notes. Just before boarding my flight I received a phone call stating that they had found a bird in the grill and it had broken the grill and I would be charged for the repairs. I was then sent photos and aside from seeing a small bird (finch type) inside the grill, I could still not see any damage to the grill. If the pictures could not show the damage then how can I be charged for repairs? I have been using AVIS for many years but never again. Upgrade me for free and then charge me falsely to repair the more expensive vehicle! I will never use them again and as per the other reviews, this is a widely used trick.
