SIM swop taken 8days still not complete, why?

I recently got a new phone and had to upgrade my SIM as the new phone requires a microSIM.<br> Last week Monday I got the SIM and called 173 to do a SIM swop.<br> I answered the questions and was told to wait 2 - 24 hours...<br> It is 8 days later and despite my calling EVERY DAY it still has not happened.<br> The excuses from the Call Centre \Champions"have ranged from 'the system is down' to (yesterday) 'there is a problem with RICA' - weird since I RICA'd the SIM when I bought it.<br> Each time I have called I've been told that they've 'escalated' the query - no idea what that means since it is STILL not resolved.<br> Please can someone from MTN contact me immediately"
