very unhappy customer

i am really ****ed with what multichoice has done to me.I pay my account every month on the 25th and to my surprise my account was suspended on Sunday 01/12 .When i went to the branch to enquire why did this happen as i know my account is up to date only to be told that i was overdue with an insurance which i am not even aware of.When i told them that i dont not have insurance they said to me that the sent a letter which i never recieved and the showed me a copy. My question is how the hell do you subscribe someone into something without their consent.Is that not ***** ? If i wanted insurance i would have gone to them to ask for it not for them to decide that for me. And why suspended my account with is up to date for a stupid insurance which i dont even know of . I have never been ****ed like this in my life i am going thru a lot already and i must deal with ********** like multichoice. I need this to be resolved and my account opened asap otherwise i will take this futher.
