DSTV keeps on billing without active connection

My service was suspended, after multiple phone calls they informed me that I can only downgrade and then reconnect my service on the 1st. I phoned on the 1st, they said I must pay the premium amount, and can downgrade then. Totally different from what the previous person said. The guy said sorry but their rules changed. They also keeps on billing me, although I have no service. My account is R200 more in two days. I am fed up with such incompetence!!! How can they keep on billing me without a connection???
