No service since 1 Feb. Problem cannot or will not be resolved

I wrote a review on 5 Feb about a Error E16-0 on the Extra view. The service has been disrupted since 1 Feb. Multi Choice did call me back on the problem the next day, but I was not in Pretoria, they promised to follow up at about 20:00 which did not happen. I have followed all the USSD options and the internet option to no avail. I have called the help desk numerous times, and been promised that the problem be escalated, this has not happened. Tomorrow, with be the 9 th day that I am without a service I pay for. I have pleaded and begged for help, to no avail. Please, what must I do to be helped. is this a standard way of dealing with customers?
