PLEASE CANCEL MY ACCOUNT!!!

I am trying with tears in my eyes to cancel a contract with tracker I never asked for, I bought a new car and had a tracker fitted thinking that it was a device that would allow me to find it should it be ******. <br> I spoke to nobody from tracker, the first month I got a bill from them, I then queried as I thought the unit was paid for. They said someone would call me... nobody did<br> Eventually last month again I tried to cancel, spoke to Prudence who told me I would need to pay once more in September because they bill like that etc. I was not happy but said ok<br> this week I called to confirm they said that someone from RETENTIONS will call me, nobody did. <br> They don't even have a cancellations department they keep saying that they will get retentions to call me... Guys I don't want to be retained. <br> I am tempted to put a stop on the debit order but know how that works because they will then carry on billing quietly until you are handed over for not paying the account. <br> I am at the point where I want to name the car dealer I bought the car from to shame them and hopefully sour the agreement they have with the car dealer to save future car buyers from going through what I am.
