We got your money, why should we care?

Good day. Telkom Mobile contacted me with a mobile internet solution offer which I accepted. When the router arrived it was broken in the box. I reported the matter and didnt hear a word for 2 weeks. Eventually they fetched it but again no word. Eventually it had been a month. SO i called and asked them to cancel the whole thing. I had not yet begun my 7 day risk free period, I had not even activated the friggin sim, but they STILL charged me the end of the month. All I wanted was a refund on that but each time I call I get the run around \Well notify the person responsible and they will contact you."Then when I follow up the call is closed saying they could not contact me or insufficient info. I gave them 3 numbers"
