Tracker Unable To Tell Me My Physical Address & Where My Car Is

We sold one of our contract vehicles, and requested it be deactivated with Tracker. A few days later, the vehicle still appeared on our contract, as it had not been deactivated like we had asked. When we called Tracker to ask why it had not been deactivated, a representative told us that because we had paid the premium, the cover would last until it ran out. We cancelled that call, and called to try and speak to someone else to ensure the car was deactivated. The next person was unable to confirm what our physical address was with Tracker. The second car we had on contract, which was at our physical address at the time of the call, was not able to be detected, or the address was not able to be identified by the Tracker person spoken to. On the Tracker App, our physical address details were blank. When attempting to add our details, Trackers App could not find our physical address. It's obvious Tracker isn't what it promotes itself to be. The staff incompetency on the telephone at the customer care line is beyond frustrating to deal with. I have now cancelled our Tracker cover entirely.
