False advertising and slow response

Telkom advertised in march that if one subscribe to showmax and have a telkom account Showmax won't take data. Do I contacted telkom customer care to ask the about it and they said I do not have to subscribe for anything. Today my data is used up and I contacted telkom and now they said to me no its only for new customers. So basically They ****. 4 Months ago I opened my account and they billed me with a bigger package than I signed on and I contacted the call center and they said I have to go in to sort this problem and I did but still no feedback after a month. Very poor service.
