So very disappointed

Good day Yoh I am extremely disappointed with MTN in Mall of the south its Day 4 today and they haven't done my sim swap properly last timeI had to do a sim swap service was amazing but this time around I am so disappointed to a point I am looking for a better proper network provider.I have been with mtn for a decade and 9 years well I am just a number to them not a family to the so called booza network. I'd be happy to get a better network that values its customers .
