Telkom and SellDirect

I am a long standing client with telkom, used to be very happy with the service. Then SellDirect contacted me for my upgrade. A phone was sent that I did not want. After many complaints, no-one assisted me. Randall from Sell Direct activated the sim after I asked him not too. I am now stuck with a phone that I do not want and a huge account I refuse to pay. Let s see if Telkom helps me sort this out.
