I asked for my account to closed.

On the 1st of march I received a call from a private number,no one spoke.and the a few minutes later I get an SMS from homechoice saying my number has been updated.I called them I was told that the system shows I had called in to update details.I asked for my account to be blocked about 2 years ago and for then to stop sending me messages. Clearly someone phoned mw from homechoice..I need my account to be closed as I have no intention to buy from them again..last time there was a ********** purchase on this account under similar circumstances like yesterday.when I was told I called to order when I didn't..what do I have to do for homechoice to stop being a nuisance to me. What makes it worse is that the call center staff is so unprofessional. They never give you any comfort that they will do what they say they will do.can someone tell me what happened with the call I received,get a call recording of that call so that we hear exactly what happened in this call that I supposedly made to update my details. I need to know.
