MTN - unsuccessful sim swap experience

I experienced the worst customer service with MTN recently while trying to recover my phone number after my phone was ******. The sim swap process is meant to be convenient so that I can protect my original number, but all my attempts to perform a sim swap were deemed futile. I attempted a sim swap 3 times in one week, due to poor assistance from staff. It reached a point where I was constantly being referred to the call center services after visiting branches, only to discover that call center agents are not allowed to assist with sim swaps. I still don't have my original number despite making three visits to MTN to resolve the issue. I've been extremely patient, and now I have exceeded the amount of sim swap attempts allowed. The staff weren't pleasant in all my revisits and I was treated with no consideration or urgency. A very horrible experience. I'm contemplating changing network providers because of this.
