Charged for Accident Repairs

Good Day,<br> <br> I wasn't happy when i received my bill from Avis which stated Accident repairs to the value of R 2151.42.<br> Upon inquiring about this, i found out that there was a slice in the left front Tyre. <br> When i received the car it had noted that the left hub cap had been badly scratched, that the the front and back bumpers had been scratched as well.Surely the person who had badly scratched the left hub cap would have caused this and perhaps the Avis guys never checked it properly when it came back.So then i ask for the photographs of the car before i picked it up and get told there aren't no photographs of before and but only now.Well that is the worst excuse.Surely a company who rents cars out, documents the damage that has already taken place on each vehicle.Because of there being no proof of damage before hand, i believe that i'm paying for someone else s negligence. Also i got told of the damage on the car, but no representative at Avis actually went around the car with me which i thought was also abnormal.If they had gone around with me, perhaps we would have found the slice.If i'm lying why is there no other damage to the car?
