******** debit

I lodged a request for the cancellation of my account with CarTrack, was told that I will pay R2650 to cancel which I didn’t have a problem with..this morning I woke up with a notification saying that they debited R850 which I believe is for re-installation of a tracking device to the new vehicle that I bought which I didn’t concern to. I specifically requested that my account be cancelled, I never said I want a reinstall! Who gave you the authority to debit R850 because I don’t remember giving you the authority to do a re installation on my new vehicle! Why was I debited for something that I didn’t ask for?did I anyway said that I want to use your company on my new vehicle? Did I not say that I want to cancel the contract?why then did you ********ly debit my account? Who in your accounts department authorised this debit of R850& for what!!!
