Netstar Cancelled my Tracker without my knowledge

I am very angry at what netstar did to me,few months ago I noticed that my tracker on the car was cancelled without my know,I contacted them and they advised that Dotsure instructed them to cancel the tracker and I have it in email that dotsure has taken up on them to pay the outstanding balance of R1927.27 after instructing Netstar to cancel the tracker because they do not have any contractual agreement with me. Today I get a call from Nimble collection telling me that my account was handed over for collection and I have to pay the outstanding balance,What!!!!!!!!

Netstar please don't play games with me, I asked for a recording,or an email where I was requesting the tracker to be cancelled you failed to provide it, please fix this mess because it's messing up my Profile.
