******* debited account

My wife and I rented a car on the 21st of December 2015 and returned it on the 25th of December 2015. We paid a deposit if +/-R3000 which was to be paid back to us in 3to 4 days after we returned the car. The money was paid into my wife's account while on the other hand they debited R2028,90 from my account. I have been phoning them almostevery day asking for my money back and no one helps me to get it back. I even went to their Johannesburg branch but i was told to refer the matter to their Cape town branch.<br> Please help
