Shocking service Sell Direct

My telkom mobile contract was up for renewal & i was contacted by Sell Direct ( stating they are an agent of Telkom) I agreed to the contract and on 2 weeks passing I enquired with Telkom and then realised Sell direct do not offer the same contracts as Telkom. I had actually initially tweeted about my upgrade and it was Telkom who gave sell direct my details. I received a ph different from what I requested and Telkom refuse to assist and I cannot get hold of Sell direct on their ***. there is no answer. I would like to return this phone immediately! This is so infuriating as I have been deceived by Telkom as they got Sell direct to contact me and I am stuck with a phone I do not want from a supplier I cannot get hold of.<br> Sell direct either contact me or provide me with an address for me to return the phone!
