Tracker Mileading and Misrepresentation

I requested to cancel everything on my Tracker in May and received my cancellation letter. They still kept deducting money after that for several months. When I enquired about it because I explicitly asked them to cancel EVERYTHING. I was informed that was for Tracker Care Guard and they are a separate division. Although my debit order refence shows Tracker they are not Tracker- (misrepresentation and very misleading). I should have cancelled with them. They will not refund my money. Which bring the question: If I requested a cancellation for EVERYTHING and are no longer a client of Tracker, how can they still deduct money for a service I didn't use or received? So, if you take my money, you are Tracker but when I cancel and ask for a refund you are not part of Tracker. I'm feeling deceived. I was misled by a company that was supposed to give me peace of mind.
