Unauthorized Debit Orders

I have had a tracker account with tracker for about a year now and after my car got damaged I have sent numerous emails to car track informing them of my wish to cancel my contract with them as my car was no longer working.

On numerous occasions they kept debiting my account, although i kept reversing the money, i feel that my emails was never taken into consideration and having to return debit orders affect my credit history negatively and the bank charges are too much for me, I would like this matter to be resolved as I no longer wish to have an account with them. I have proof of numerous emails i have sent to different email addresses.

I am very much angry and disappointed about this.

Overall I had a wonderful experience with them up until this.
