Incomplete Agent

Worst service ever, I don't know what happened to multichoice. My husband went on to self service to find out how much we have to pay for August . The lady assisted him said it was 495 he paid 500. 2nd of August dstv was disconnected. He phoned again agent told him an offer was loaded re connected us again. We asked her if it's been shorted out and she said yes all shorted only have to pay end of August for September. Guess what we have been disconnected again. Today they told us that we need to pay outstanding amount. Is there any agents at DSTV that knows what they doing. Asked them to speak with manager still waiting for them to call back. This is worst agent serving ever
