Horrible service 790

I am not happy with what cartrack is doing,they gave me a horrible service providing the wrong information. even when I asked to speak to the supervisor she didn't help me she had attitude. They debit amount in my account anytime they want to and they debit any amount they want to debit not the actual amount. The guy who I had a conversation with who is Sello Motadinyane at the Accounts department was even laughing at me which made me angry. Am not happy with their service at all they don't know how to threat customers.
