Unacceptable and Shocking Service

I left two very negative reviews last week, however now, it only gets worse. When i hired the car they took a R5,000.00 deposit, fair enough. My Credit Card provider has informed me that they have taken ( banked ) the full amount of the deposit. This amounts to theft. i have emailed their Customer Service Manager, Smangele Mbele, four times a week ago, i still do not have his reply, i then emailed him again twice since last Firday, he has not bothered to respond. My advice is not to go near this company !!
