DISGRUNTLED VICTIM OF WORST SERVICE

Installed a tracking device in October and it only worked for less than two weeks and it stopped working.I booked with the scheduling dept 3 times and they decided to come to repair zero apologies but they continuously collect money every month today i decided to cancel the services and they have been throwing between fleet department and scheduling department since morning. I asked for customer complaints and was told there is no number for customer complaints i asked for the supervisor apparently supervisor is never available now after seeing their true service i want to move the whole fleet.
