False billing

I recently scaled down my DSTV subscription to Easyview with an Extraview connection. This setup should cost me R 119 per month which I have paid on the 30th of January, however now Multichoice sends me messages via the decoder and by sms that I need to pay R 193 before 5 Feb or my account will be suspended. Checking the self service app online does not help because it does not tell me where this *****ulant charge comes from it only states that this amount is payable. I tried phoning their call centre only to find that there is no option for querying account issues at all, only a prerecorded message that tells you how much \owe\". This is the worst maladministration I've ever encountered. Apparently Mutlichoice beleives that the customer should be avoided at all costs. If I get no response from them via this forum it will clearly show me that they're not interested in my business. "
