MTN bad service

I went to go upgrade my phone on the 19th of April 2015.<br> I upgraded to the Samsung S6, a SIM swap was required and I was told that it would take up to 24 hours for the SIM swap to be completed. Up till today the 11th of May 2015 I'm still waiting. Between the day of the upgrade and today, I have been to the shop/branch that helped me and even called into the call centre. On the 5th of May when I called in for assistance on was told that they couldn't help me and that I needed to go to the shop/branch again which I have done many times before calling, at this point I was fed up and demanded to be put through to someone who could help me. I was then told to send a fax to Hleketa, at this point I asked the person who processed my upgrade to the fax/E-mail. At this point I'm tired of waiting for MTN to process the request. I want this issue to be resolved immediately. <br> Reference number: ***
