AVIS - rental agent sluggish when i returned the vehicle

i rented a car for one week through an agent with full coverage. Upon returning the car i was told by the inspection agent what can i tell her about the two dents on the bonnet. I could not tell her anything cause when i took the car they were there. Should i have said anything else contrary i would have been charged.

I asked her to check on their system about the dents and she did and found them and said, "oh there were there when i took the vehicle". I asked her why they don't check their system first before asking if a customer knows about any damages on the vehicle, and any new damages will be pointed out to the customer. SHE COULD NOT GIVE ME AN ANSWER This is what i think happens, why they don't visit their hand-held system with the car details. Avis capitalizes on our ignorance especially when you have taken comprehensive cover and will charge you even for old damages on the car that you might have missed, basically double dipping or even triple dipping for the same damages. Tell your staff to be courteous and give straight and honest answers, they should not be evasive in their responses. This review would not be required if she had the handheld device on her to check, but maybe she was just lethargic to go and fetch it about 30 meters away from another agent. The car was a T-Cross and it drove beautifully.
