ignoring my cancellation

I sold my BMW more than two years ago and I have requested that tracker cancel my account 3 times. I am promised that someone will phone me back to finalize the cancellation every time, and no one ever does. The debit order has even gone up! It is a terrible way to make money - making it impossible to cancel the contract! The faulty debit orders must amount to R2500 plus... Please could someone contact me and cancel this contract? <br> <br> Sad that I have to resort to Hello Peter to get a reaction...
