Number taking 2 weeks to sort out

I made a contract with MTN from the istore on the 7 November. Because MTN servers were down, my Contract was only approved on Thursday last week, 12 November. But some problem happened on MTN side when it still showed as prepaid.<br> <br> I was porting my number from autopage. Only on Tuesday it went through and I got my phone, using my current sim.<br> <br> My number was converted to prepaid, when it was specifically asked to change to number-for-life.<br> <br> I find out today my number is still prepaid, and I am now sitting with my new phone with prepaid, having to load data and airtime at my cost. <br> <br> They said they would investigate and get back to the istore lady on Monday!! <br> Why does it take this long to convert my number to number-for-life and put me on the MTN contract????<br> <br> Who is working at MTN?? NOONE??
