Complaint against Avis

I rented a car from Budget. When I returned the car I was told that the bonnet was damaged. I requested to see the damage and I was told that I must stand at certain angle because I would not be able to see the damaged where I was standing. The person who was inspecting the car also told me to feel the car for the dent.<br> <br> He told me to sign the papers to acknowledge the dent and I told him I was not taking the responsibility but acknowledging the dent. Avis sent me a bill of R 2 795.38 and threatens to forward my information to credit bureau. <br> <br> I do not agree that I damaged the car and there was no damage to the paint of the car.
