Poor customer care

Totally unhappy with the service I'm getting at the MTN call centre, for the past 6 days I have been unable to make a living because my business is mostly cellphone based and my network provider MTN has failed to do me a simswap as my phone got lost, how can the network take more than 6 days for a simple sun swap, even after sending through an affidavit as well as ID copy because of some security question , I was told 24 to 48 hours but it's already the 4th day, what a way to start 2020, the number in question is ***. Never before have I thought about this porting thing but seriously I doubt the other providers will drag their feet this way
