No proof of damage - we did not drive it in hail!

My daughter hired a car for us - we returned it and the guys who took the car in did not find anything wrong! As we got onto the plane they sent a message to say there was damage - she phoned back immediately - nobody answered the phone!! Next day she got an sms to say they were debiting her account R4339.13 for damages I phoned and spoke to a lady (forgot to get her name) and she said she would register a dispute - next day it was debited to my daughters account - I phoned again and there was no dispute registered - I then asked to speak to the Manager - spoke to Cathy who said she would phone me back in 20 minutes - she didn't - I phoned again to be told she is trying to get photo's of the damage (hail damage to boot,roof and boot)- then the emails started -back and forward waiting for proof - eventually Cathy emails me to say the car has been repaired and because it was under R10000 they did not take photo's - I have been emailing them and asking for some kind of proof that it was the car that we were driving - they don't even reply to the emails!! While we were in Joburg - we never drove in any hail and we parked the car under cover - there was no damage when we dropped the car!!!
