A SIM SWOP that is taking a week to complete

I lost my 3G Sim during a recent move and had to do a sim swop. From being promised that my new sim card would be active within three hours, I am now a week down the line and my internet is still down.<br> <br> I have received two call backs in the week and only ever get feedback when I call them or camp in the nearest store. Nobody seems to know what is wrong and I get pushed from pillar to post with no resolution. MTN was blamed for four days and eventually had to do another sim swop on Thursday. Guess what - this has still not worked.<br> <br> I work predominantly from home and need the internet connection - a fact that nobody at MWEB seems to understand. I am purchasing daily internet bundles which has accumulated quite a cost. <br> <br> I am at my wits end. I have been a client of MWEB's since 2008. Seems this loyalty was for nought.
