bad service and client management

Another complaint about tracker within 6 months! I received a phone call from tracker a few weeks ago asking if id be interested in a new product which would allow me to contact tracker for help from anywhere (not necessarily linked to my car). I was busy and not able to give my full attention and said no thanks im not interested currently. I have now received an email saying my contract has been cancelled as requested by me! when phoning tracker to enquire what has happened and how /when i requested this...the service agent referred to one of my previous online complaints, whereby I indicated that I hadnt been helped and that i might terminate my contract if not helped (this was a threat to try and get more urgent help from tracker) - not me asking for them to cancel my account!! I am so fed up with tracker and there service and how my contract has now been cancelled! and I need to follow up and investigate why and how to resolve this every time. No one seems concerned about client retention at all!
