Avis seems it fit to charge for bogus days

My insurance company arranged a replacement car for me whilst my car was being repaired. They had arranged this from Avis for the duration of 3 weeks.<br> The rental was delivered to the panelbeaters at 10 am. I was explicitly told by the Avis employee, Abington, that upon me picking up my car, that an Avis employee would pick up the Avis rental car at 10 am, again at the panelbeaters.<br> The day of me picking up my car I waited more than an hour, and no one from Avis appeared. I phoned the call center, and was advised to to leave the keys with the panelbeaters, and that they would pick up the car.<br> I then forgot about it.<br> When I later checked my credit card statement, I was amazed to see that I was charged an extra day! <br> I have since had the joy of trying to sort this out with the call center and a customer relations assistant. They have yet to reply to my satisfaction, which would surely be an immediate refund.<br> <br> Mr Avis...this is nonsense, and I want my money back. This is your mistake, and you are trying to pass the buck. You got 3 weeks of rental out of me...i would be sure not to use you again!
