Miscommunication,unauthorised add on facilities

I Joined multichoice in July last year if my memory serves me well and took out the HD Compact option which is Currently R320,the installer completed my personal information as I was working and could not do it personally.I have been making monthly payments of R320 through one of their partners pep stores. In December I did not make any payments only in January I still paid R320 regardless of pep stores advising me only R260 was due.when I came back home my account was still suspended and I called the call centre for reconnection. Only then it was brought to my attention that I have insurance it has accumulated and Now I'm owing them. It an expectation that they should have communicated to me that I have making short payments. And according to my knowledge even though the installer acted on my behalf a FAIS accredited consultant shud have still contact me and briefed on the insurance Policy I had apparently taken up.I expect multichoice to be transparent and accurate with the information about clients account together with their partners and not indebt clients unnecessaryly. My ref number is 41088I32. I expect multichoice to to cancel this policy and write off all accumulated premi
