poor poor service

I called to have my tracking device changed into my name earlier this year and advised them i cant seem to pick up my car on the app and a new device was installed and i advised them listen i think something is wrong with the device and was informed nothing is wrong i had my car repaired not long after this the alternator burned and this happened again this past Friday the mechanic checked and informed me the alternator burnt but asked the auto electrician to check it and informed me that the device is connected to the alternator to charge who does that as far as I know it shouldn't be connected directly to that it must be connected to the battery now i must pay for the alternator to be fixed and i need this device connected properly i am so frustrated and annoyed with the service i am getting from you guys and it will cost me another 1500 or more to repair my car and i dont have that kind of money just laying around.
