You are handed over

I cancelled my insurance with dial direct effective end july 2015. When i called dial direct they confirmed cancellation date and that i had no obligations regarding 2 tracking systems installed in my motor vechiles by tracker which were part of my monthly premiums as more than 2 years had elapsed since they were installed. As i was getting new tracking systems installed with new insurance provider i still contacted tracker and advised cancellation of dial direct as matter of courtesy. I then as 1 august migrated. I subsequently travelled overseas for over a month and recieved many calls from tracker to advise i was in arrears. After contacting the call centre 3 times and after explaining i never paid them a oremium etc i was assured my cancellation calls and queries would be retrieved and matter sorted. Needless to say they never followed up. To be clear i never paid a seperate premium it was part of insurance policy, which when cancelled all oarties were notified. Now i am being bugged incessantly as tracker decided its easier to hand me over to there attorneys who when i advised there was a query fobbed me off. Tracker customer service ******* and feedback non existent,.
