Worst service ever!

I went to MTN on Sunday morning to upgrade my headset.<br> <br> After over an hour of standing waiting around upgrade was finally put through - to be told my sim swop/activation would only take 2-4 hours.<br> Cut through to Monday morning the sim is STILL NOT active. Tried several times to get through to MTN call centres - the line constantly was disconnected. I did not get through to a consultant once.<br> <br> At 6pm I tried calling again, got through to a consultant finally, to be told no the sim swop failed!!! So they need to try again. It is now Tuesday morning, 11:29 am and the sim card is still not active.<br> <br> Through this whole process I've emailed, contacted over social media and called call centres and NO ONE has bothered to help correct this situation or even contact me back.<br> The lack of service with MTN is shocking, I'm ready to cancel this upgrade and move to another network. <br>
