FAILURE TO COMPLETE CUSTOMER'S REQUEST

I was called by a Telkom agent offering me a deal on the Altech Node. When I received it, it was not what I had agreed to. I was told I would pay R149 per month, but its only been 3 weeks and they have already deducted over R500. I called the call centre in Randburg to cancel my contact. I spoke to Malerato Ledwabe and she said it would be resolved within 3 working days and after those 3 days I was not even called for an update on my request and they did promise to call. I have been calling everyday since and I have been treated terribly. I even spoke to the supervisor named Tshidi, she wouldn't give me her last name. I called to cancel within the 7 working days of receiving the Node and I was told if I did that I would not incur any charges. Hellopeter please help me resolve this matter because the clock is ticking and they could deduct a further R299 which I did not agree to, I agreed to the R149. Thank you and I hope this matter is resolved urgently
