Regret renting a car with Green Motion Car Rental (Kenings)

Am so disappointed, worst car rental I regret trying it out. I had a stretch on the bumber which they charged me R7337.21 and they had my deposit of of R7300 which I expected that they would charge my credit card R37.21 which is the difference between my deposit and their claim charge but instead they charged my credit card R3837.21 which means they now owe me R3800 I tried calling spoke to the lady called Brenda from claims she mentioned that she will talk with the invoicing team. I still have not heard from her.

I need somebody to call me and advise why was my credit card charged more than the amount due to you now I have to wait for more than 21 days. Call me on 076 209 2892
