Car hire poor service and rip people off

Worst company I have used. Service terrible. Take money from my account without email or explanation. I had 3 hubcaps ****** charged me R3500. I gave the car back full of fuel. They indicated that it was received full. I have a payment from my account to show I filled it at engen now Cape Town airport. Today month later they debit my account for fuel 412 rand. No communication. I feel I have been **********. They take money as they want to. Awaiting some sort of corrective service. I will not recommend them.
