Poor service from Cartracker

I have been using cartracker for the past 7 years but this year they failed me dismal, in April i noticed that my tracking device was not working than i reported the issue to cartracker but they never responded to my emails, whatsup group and contact center up until i decided to reverse their debit order cause i knew that the only thing that they care about is the installment but clients complain and their concerns are not taken serious. For the past five months my car was without tracking device but every month Im expected to pay for something that is not working, i tried to speak to their complain department but still i was not help at all. I end up canceling my relationship with them because i realize that they don't care about clients but what they want is to rip us off even during difficult times like this still they don't care about clients. I hate them with all my heart and im intending to take this matter to ambudsmam cause wr ad clients they take advantage of us. Even if you decide to cancel their service they don't care, no questions or any follow up, just to ask the client why is living their services like they don't care at all.
