Billed for a scratch without being informed

Good morning

I am lodging a formal complaint against avis Amanzimtoti for billing me an exorbitant amount regarding a scratch under the vehicle.

When i returned the vehicle, the guy told me everything was fine, before i left he then mentioned there was a scratch on the underneath of the cars bottom black bumper.

This is my first time hiring a car, i didn't know that i needed to look underneath the car aswel.

If there was no scratches to any other part of the car, how can i be sure that it wasn't there before???

The guy then went on about another scratch, as if he was looking for other issues.

I am a female driver, had i known avis manages their business in this manner i should have brought a mechanic and panel beater to confirm the vehicle first.

This is ******ion.

The guy was rude and unhelpful, he told me that he will call me if there was any problems regarding this issue, if i dont receive a call then i should take it that everything is in order and the refund will go through.

Its been a week with no phone call and no refund, i made a call to avis this morning only for the lady to tell me that i have been billed more than R1400 for repairs and the rest of the funds will be deposited.

I will not take responsibility for a scratch under the vehicle which i had no knowledge off.

I want to know how is avis going to rectify this situation by COB.
