********* and appauling service

Had a vehicle hired with avis via insurance, as a courtesy car. Received the vehicle but when it came to being returned, they charge me incorrectly for a delivery charge which i am still awaiting a refund on. Then we receive an email for a fine and they say its R1500, when we asked for proof, the amount then drops to R750. Then we get charged R334 as an admin fee for the fine. How the hell do you guys warrant charging that amount of a fee when all you do is get an email of the fine and then forward it on to the customer???? As far as i'm concerned this is **************** and clearly Avis is one of the most ********* companies i have come across in a while. 3 instances with one client where they deliberately are wanting to ***** over the clients and make money unjustly. And your so called message at the call centre where if you send an email, you will get a reply in 24 hours.....just more lies from avis. And no senior manager available either when i requested to speak to one when i called it. My next steps, cancelling the courtesy car option from my insurance, reporting you guys to the ombudsman and advising all my colleagues, friends and family to never ever hire from you guys ever because of how ********* your'll are. And reading from the comments on hellopeter, seems as if my sentiments are justified as you have *****ed over quite a few clients when it comes to money.
