Terrible Service and withholding of deposit.

I really wish I could give less than a 1 star review and reading through all these reviews it seems I am not alone. I rented a car with Avis through my insurance and from the get go the service was absolute ******* not to mention the tuna can ******* they give you to drive with. They delivered the car we did the inspection no damage was on the vehicle then they had technical issues with the deposit payment and took the car again and delivered it later the same day. No 2nd inspection of the vehicle was done. When I returned the vehicle they said everything is in order and my deposit will be paid back in 7-10 working days. Now 2 weeks after I returned the vehicle I get a sms stating that we damaged the vehicle, does i take 2 weeks to notice? You want us to call you but your call centre is not reachable. I am extremely disappointed with Avis, how can you do an inspection then drive off with the vehicle not do a 2nd inspection and then blame me for damage?
