Account Debited twice after cancellation of servic

I sold my vehicle on the 10 of June, to which Tracker was notified prior and after this occurred. They said there was no need to have the unit removed as they would just switch it off. They also said I was liable for a settlemnt fee which Im okay with. They never called to advise of that until the next month after deducting yet another subscription. <br> <br> Two weeks later I could still locate the vehicle to which they said they will deactivate the account. Today 20th July they still haven't done that. I can still locate the car I sold more than a month ago!!!! <br> <br> I got a letter to say the settlement fee was R 800.00 which I said all is OK, will pay before the end of the month<br> <br> To my surprise, this morning they deducted 2 x subs (R 431.82). I called them again they say we will keep debiting your account until settlement fee is paid. I told them I'm reversing the transaction and they said they would black list me!!! Like really?!<br> <br> I HAVE ONLY BEEN ADVISED OF THE SETTLEMENT AMOUNT LESS THAN TWO WEEKS AGO!!! (and Im paying monthend!)<br> <br> Stay away from tracker service appalling!!<br> <br> <br> <br> <br> <br>
