VERY BAD SERVICE AND FAILURE TO TERMINATE REQUEST OF CANCELLATION

I have on 3 occasions attempted to contact Tracker to cancel my Vehicle Tracker that i no longer need and both occasions held for more than 10 minutes, first time a consultant answered and claimed i am in the wrong department only to be put further on hold. I get a sense that there is a deliberate attempt to delay cancellation of an already expired contract that is currently month on month. Rightfully so they debited me even though i have attempted to get a cancellation. I need the DEBIT Reversed and this cancellation effected immediately. I have wasted enough money attempting to contact Tracker. Please cancel the Contract effective immediately failure i will be reversing the DEBIT Order until such time you act on my request. My details are listed below I will await confirmation of the said cancellation.
