Poor customer sevice

I have been trying to cancel my tracker for 4 months with no assistance. my account went to arrears. I was referred to their attorneys, i advised the attorneys that i tried to cancel my contract which was not cancelled and i had to pay the arrears and still the contract was not cancelled. Now i have to pay again extra funds on top of the contract that they do not want to cancel. They offered me a 50% discount which i paid and still they call me and say i still have outstanding balance. I asked about the cancellation of the contract that was initiated 4 months ago and i have been transferred to another department which told me that my cancellation will be done next month on the 27 including payment for the month. when i ask about the initial cancellation that i requested and the request from their attorneys i get no answers.
