Funds not returned

Avis centurion, I was first incorrectly billed then without my permission debited from my account leaving it into a negative and now being **** to.. I was told last week Thursday that my deposit will be released I phoned and confirmed this with jannie at avis centurion he's said that the funds were released and will be in my account the next day, the day passes I then go in on Saturday to avis centurion and he said it will be in after 12 still nothing happens I call him on Sunday and he says he cannot do anything and then says he will email me proof that the funds were released. I wait but no email I then call back and he says I.T is working on it. Avis Give back my money!!! <br> I have been dealing with you guys for sometime now but this is pathetic honestly. My family and colleagues use avis and they are not happy seriously they are disgusted. I have used this company for the very last time now. You are going to lose a lot of good clients because of this pathetic service and the lies these people keep speaking
