No assistance at all

So its been 39 Days thats 1 month + that im not able to perform a simple thing as a Sim Swap at any of the MTN Branches including Mimosa Mall,Loch Logan nor President Hyper I have to go to the store EVERY day in working hours just to hear that i have to wait another 24 - 48 Hours so hows it possible that its been going like this just to get assistance with a normal contract Sim Swap unbelievable ? yet I still have to pay for this every month not being able to even use the sim card Beyond my understanding
