Tracking Unit not active - Netstar could not care less

My App stopped updating on the 25th of September 2020. I called in (on the 28th) to have the unit tested and I was informed that it was "due for an upgrade" hence why it was not updating. I was then promised that a technician would be in contact with me but that never happened. I have been calling everyday since the 28th of September 2020 and I keep getting the same response - a promise that someone will call me. I am driving around with a unit that is not active. I am left with no choice but to cancel my contract. If Netstar is this useless with a simple unit replacement, I can only imagine how useless they are when it's time to recover a ******/highjacked vehicle.
