Disappointing service

Disappointing product, I installed a car tracker unit years ago for my car with Tracker connect. I recently replaced my car battery and to my surprise I did not receive an alert message from them to find out whether everything is in order. In the past, when i would replace my battery, I would receive a communication from them immediately. It was not the case this time around. 4 days later I had to phone them to find out what was the problem. My concern is not being aware that there's been an issue with the unit and not being made aware of it by Tracker connect company. So basically, I have been paying for a service that has not been working and who knows correctly how long?
