Compilation of errors regarding balance

In short, I unsubscribed voluntarily as I would be out of the country.(Starting from 28 May 2015 to when I would contact Multi Choice and re-subscribe) I was informed to also do a stop payment at the bank, which I did. Upon my return two subscriptions went off (28 May 2015 and 28 June 2015) and I had the bank return them. I was contacted by no less than 6 agents regarding reconnecting, however I refused until my balance had been cleared, and after retelling the story to each and every one. The last agent I spoke to was Natalie on the 30th or 31st July 2015. I reiterated her statement of the balance being amended to zero, before I would reconnect or re-subscribe. According to my balance which see-sawed from R2000 odd rand to R920 odd rand back to R1450 odd rand, I have had no joy. They do not respond to complaints or billing enquiries of which I have probably sent 3 or 4 this month. It has been almost a month since speaking to her and yet it still has not been corrected.
