Misrepresentation

In September 2017 I wasn't called by an agent to renew my contract. I agreed to renew the contract telephonically. What wasn't not mentioned is that it was a three-year contract and the data was for three months only. I only realised that it was a three-year contract when I received the sms. I have not received/taken delivery of the promised hand set. I have tried telephoning MTN no less than three times. Each time I was told to speak to the retention department. Each time I was on hold for twenty minutes. The waiting time is absurd and indicative of what MTN think of their clients. When on repeated calls I told the call centre that it is impossible to speak to the retention department, they sent e-mails on my behalf. Over and above that I have sent two e-mails. Last week I went to a MAN outlet in East Gate, hoping they would be able to assist. The consultant sent an email as well. To this day I have still not received an acknowledgement, let alone a solution. I seek to terminate the contract and I do not want to deal with a company that treat their customers with contempt. Please assist.
