BAD SERVICE

I am really unhappy, on the 19 July 24 I joined cartrack hoping for the best service, I was told installation is free, and the monthly premium is R219, to my surprise I got debited an amount of R320 yet the Technician who installed told me i will only be debited the Pro rata fee which will be less than R219 since its almost month end. I called in today to find out why was I over debited and I spoke to a very rude guy named Simphiwe Ngcobo in the accounts department who then decided to transfer me to client services and at client services they told me they do not know why he transferred me there.
