AVIS stole money from my account

Good Day Sir/<br> On 2015/06/08 I booked a Hyundai i10 at Capetown international airport Avis branch. When I picked up the car there was some scratches which I reported and at the drop off zone when the inspectors saw the Hyundai i10 one of them jumped and told the other one \is it the same vehicle? "and he told yes . then they just came and went to right front fender (without inspecting anything else )and told me look this fender is shifted slightly and I told them I didn't have any accident then they told me to write \"" the fender was like this when I picked up the car \"". I dropped off the car at 12:30 and next day at 14:00 I just received an SMS from AVIS telling : I must pay R 2616 for the damage I didn't do to the car. I tried to call everyone in AVIS South Africa but they didn't answered me well. Now the amount is deducted from my account and I want to ask my Bank to reverse it back . the worse thing about this is they didn't send any document or quotation for the repair to me .the amazing part is that I booked that vehicle on Super Waiver option !! And I want to ask how it is possible for them to get 3 quotations from different panel beaters in less than 24 hours!!! ??"""
