Beyond PATHETIC service - Still waiting!

I am still waiting for my SIM card to be activated which I had received from MTN on the 30th of November. I was told that it would be sorted out by midday on the 16th of December and it still isn't. I am highly disappointed and frustrated with MTN's service and efficiency! All the Middelburg mall store has to say to me is that I have to wait and they can't do anything because they don't know who to call. I had to phone the activation centre myself of which I got the number from the customer care centre, the MTN store knew nothing about this - they are extremely inefficient and only look for new contracts but are never willing to follow up! I don't know how much longer I must wait as it's now been almost three weeks! If this is the type of service I am being offered, I would rather transfer to another service provider and never recommended MTN to any one ever again. I find this absolutely appalling being a loyal MTN customer since 2012.
