Upgrade done 3 weeks ago and still no delivery

I am really disgusted and very annoyed with the service I am receiving from Mtn direct... I app**** for an upgrade on the 4 Nov 2015 and I still did not receive my handset... I was told that I should call mtn direct to do a follow up and i've been referred from pillar to post ever since... The staff at mtn direct are beyond useless and very *********** as they have no knowledge about their brands processes and procedures... I will not pay a damn cent for something I do not have... I keep hearing that they have to authorise my delivery and that will most probably happen when the world comes to an end... <br> <br> Get your damn act together as you guys are not doing me no favour as I am paying for my device..<br> <br> There are other networks I can switch to without having stupid issues like this...
