The worst service recieved

After being a client for all this years, I’ve been calling them day in day out since May 15 asking them to cancel or come and install me a new tracker. They make promises after promises. I am paying for a tracking device that I don’t even have. The car was taken to the dealership. Today I wake up to their debit order, after telling them to cancel last week. They still going on with their monthly premium. Terrrible service providers full of empty promises
