Anyone working at Tracker?

Before I sold my vehicle I wanted to transfer the tracker to the new vehicle but they were completely unwilling to assist! It was cheaper to cancel than to switch vehicles, accordingly I requested that the subscription be cancelled. They sent me someone else's cancellation letter and I requested it to be corrected the very helpful agent agreed that I can just cancel my debit order, which I have subsequently done. Nothing works with Tracker, not the website, not the telephone lines, it's actually scary!
