Sim card termination instead of help... Incompetence

<p>I just ported to Mtn last week and I seem to be regretting the decision already. Yesterday my phone lost all network signal prohibiting me from making and receiving calls and accessing the internet etc. I called the MTN customer care line a million times and somehow one of the consultants pressed the terminate sim card instead of the reset button. I've spent last night and today making countless calls and I'm being told the same thing... switch off your phone switch it on after 5 minutes blah blah blah.. still no change. I am frustrated and not getting assistance. What am I meant to do now? I'm at my wits end really...</p>
