No Resources implemented for ****** contract sim card swopping

I cannot believe how a big company like MTN think??? I was ****** on Tuesday, both contract phones, NO ONE can help me with a sim swop, only answer, we cant help, wait for lockdown to finish! This is unacceptable, surely this is an essential service just like the other service you are providing. only 1 person tried his best to assist me but he also said, he can't do it. Surely as a big company you should have thought of resources for incidents like these? so great MTN I am without any form of communication. Very Very unhappy with you as a service provider!
