Incredible poor service

If you ever think of doing business with this company, it will be in your own interest to get their cancellation policy in writing. I cancelled the Tracker service, on their own website, with a 30 day notice period. A month later, when Tracker's debit order on my account was returned, I got a query, and I rep**** in the e-mail giving the details of the cancellation. Since then I have been plagued by calls of Tracker themselves and various debt collector services, none seem to understand that I cancelled the Tracker service. Wow, if your admin is so hopeless, how can you ever recover a vehicle??
