Extremely bad service and continuous theft by Multi-choice!!

Last year I upgraded to the explora decoder on their R529 a month package, all ws well for about 3 months, then they started missing debit dates. Every time I called to rectify this I got a long explanation about why the money was not debited, and that I would have to make payment at one of their stores or closest pick n pay and pep, then call back back so that they could link the payment. All of this at my cost. Then I was told they're having a problem debiting my fnb account, this went on for several months. Then I decided to open another account with nedbank so that I can go back to normal debit arrangement. Now they're debiting R4000 and R3000 every moth. When they don't even have packages for that much. I want them to stop debiting me, I will go back to paying cash every moth if i have to. They have suspended my services for two months now and keep calling me to reiterate the same story over and over and over again. This is giving me bad credit because they refuse to reverse them and i end up going to the bank to have these debit orders reversed. I am sick and tired of this bad service from multi choice.
