On the 05/08/2015 I rented a vehicle at Avis at East Londen Airport. I was upgraded from a Class B vehilce to a Class F vehicle. I was impressed. Then they took a deposit amount of R2112.02 which they indicated will be held for the charges and the balance will be refunded.<br> <br> On 14/08/2015 another R1501.31 was deducted by Avis on my account. The total Invoice was R1501.31. <br> In total the deduction on my ***.33<br> <br> My issue: <br> Double deuction of Deposit and Final invoice on my account. They emailed me on 15/08/2015 and said the money will be released in 2-3 days. Huge inconvenience for me. Now I must be without another R1501.31 for another 3 days. In total to date out R3613.33 for one days rental and 39km travelled.<br> I drove 39km in total for the rental period. I was charged 78.2 L (R1003.00) for this. It was a normal Dodge Journey vehicle.
