Avis deserves a full zero out of 5 rating from me.

So I complained on HelloPeter about Avis about a week ago. They supp**** me with an uncleaned vehile off the 'walk-in' lot, when they could not find the keys for the car that I had booked. The state of the vehicle was noted on the questionnaire, and Avis had no problem with the vehicle when it was returned. However, after the Pro-Forma Invoice was received a week ago, they then proceeded to deduct R600 for a valet when producing my final Invoice a day later The vehicle did about 180km of mainly highway-travel over less than 2 days, and was returned in the same state as it was received in - IE it may have had a few extra bugs on the windscreen from normal travel. Avis had no objection when the car was returned and noted that everything was fine. Avis, after being reviewed on HelloPeter were going to follow up 6 days ago. So far, I have heard nothing further from them, nor have I been refunded the the valet charge or the deposit more than a week after the vehicle was returned. Avis is the worst car-rental company that I have ever experienced (over a lifetime of rentals).
