MTN promises the world but deilvers nothing.

Further to my previous complaint almost a month ago and many promises to come back to me my problem has still not been resolved. Mantoa promised to escalate the issue but nothing happened. I was phoned by Kagiso who said he would come back to me but he didn't. <br> <br> I went to a local MTN shop twice (after being asked to do so) to do the SIM swap and still it is not working.<br> <br> I have been with MTN for almost 16 years. This is an atrocious way to treat loyal customers. Is there any reason for me to stay on?
