Pathetic service from MTN

Had to do a sim swap as my sim card stopped working. Sim swap done on the 10th of march 2021, today is the 13th of march, i phoned in 14 times to carry out the security questions on the 14th time i was told you answered all the questions correctly, it will take 2 to 24 hours for your number to be activated, this is now the 3rd day and my number is STILL NOT acttivated, phone in everyday to 135, and i get told sorry mam, it has been escalated to the manager, i use this phone for business purposes, this is the worst service i have ever experienced with mtn. I am thinking of actually moving over to another network. Pathetic service MTN.
