MTN not willing to assist with blocked sim card and sim swap

My phone got ****** on 21st March 2025, like what any person would do, I called MTN to blacklist my phone and block the sim card. So because I want to use my old number, I went to do a sim swap - I went in store the first time and was told the sim swap cant be processed because the blocking of my sim card is still pending. I was told to Call MTN - I did so multiple times and everytime I call I get a different story as to why I cant do sim swap - I’m sent from pillar to post. I have been to the store 5 times and I cant even keep count of the number of times I have called. This afternoon, I called and the agent who assisted me told me I cant do a sim swap because my sim card is blocked and I have to request that it gets unlocked - she then gave me the MTN Business number to call because apparently my number is a business number and I know it is not. The next person I called said she will escalate and log a ticket, when I kindly asked what she is logging the ticket for she said I wont under which I found rude. I asked to speak to a supervisor and she said the supervisor will call me, I asked for the name of the supervisor and she said she cant give me the name as I will harass him on social media.

All I am asking is for this sim card to be unblocked and be able to do a sim swap. The trouble I am going through is frustrating and I actually feel like I am being punished for taking the safety precaution that MTN advises which is to block a sim card when the phone is ******. I am being sent from pillar to post with no solution and no body from MTN willing to assist me.

I need this matter sorted.
