Avis just deduct money and make claim to damage.

I see that Avis deducted 313.50 USD from my account. Please can you explain why? As it should be about 100 USD. <br> Please take note that I did not take responsibility for the damage that you informed me via SMS and that I've logged a queried with you stating the following : <br> \I've rented a car from you ref E*** in Cape Town. On collection you gave me the keys and said there was no damage to the car. None of the Avis employees did a inspection with me but myself and a friend did and found no visible damage when we walked around the car. When I returned the car your Avis employee walked with me around the car and said everything is in order and took the keys. There was no noticeable damage on the car. Today I received a sms saying that there was damage noticed on the car with of R6273.43 ref: 16/122462. I did not put any damage on this car or signed for any acknowledgement of damage. I did phone your damage call centre on *** and they said they will send me an email but I still haven't received anything back yet. My current experience is that you are not transparent with your dealings as you just deduct money from my account and also claim damages via SMS."
