Tempest Car Hire *******

Rented a car from OR Tambo to go to Hoedspruit. En route we had an accident - no damage to the body work of the vehicle - rear bumper and front right wheel. When we reported it, I was told that I would then lose my "deposit" - which I fully understood. We had to get another vehicle because of the damage to the front wheel, but I was never advised of any additional costs. Without advising me Tempest then too 3 amounts from my credit card, totalling over R10,000.,00. I had to cancel my card the minute I saw what they had done and have emailed them for an explanation, getting none. If the customer has to pay the deposit, which one understands covers any insurance, what gives them the right to just take money from my account? I am really angry!!! Been to my Bank, who say they cannot do anything about it, so I am sending this to you in the hope that something can be resolved. I am a Pensioner who can ill afford to have this happen.
