Dstv(multichoice) contract account ***5

I am a DSTV customer for more than a decade now and i have never have a problem with upgrading and downgrading my channels. Last months i downgraded from family to access and on my July debit the debited the amount for Access. Today they sent me a riminder for debit of R473 on the 27th August. They saud i am owing them the balance from last because i was supposed to pay family as i dont qualify for downgrade. They said i have 24 months contract with them which stops me to downgrade or even close my account.

I dont know that dstv have a contract, what i know is that we always pay before we watch. You fail to pay they switch off your decoder.

I cant remember anyone call me and explain to me about the contract and how its works. Because i will never took that foolish contract. I am disappointed with their service and now i am stuck with a contract that i dont even know.
