Bad Service

Good day

After several phone calls and e-mails for past year and a half I do not get service from tracker. My device is not working and I must pay every month. I spoke to several people and they tell me my car is on route somewhere, meanwhile it is parked and ignition switched of in my garage. last email I sent to financeconsumerquery and still don't get fed back. The one lady said after I told her they must come and remove the device from my car, some technicians will call me for an appointment and they never did. This is Absolut bad service.!!!!!!!!!!!!!!
