CARTRACK will not or cannot move unit from sold vehicle , yet charged fee for moving unit...and continue to charge monthly for nothing... ...

Pro**** itself is good. After service care I'm having some difficulties, had a tracker in my bakkie, no problems, sold the bakkie, paid the r870 fee to have the unit moved, and never heard anything back from then, was charged and am still being charged monthly, and I don't have any service/device, called and emailed numerous times, no response , no feedback. Requested a refund on all monies paid after the transfer request , no feedback no response , nothing....so next step cancel debit order and open I debit order dispute with bank and try recover payments made for nothing...
