MTN Pathetic Customer Service - once again

My phone was ****** last week and I had gone into the MTN shop in order to do a sim swap. The consultant advised me that my account is with the legal team and has been there since April 2022 and because of this they cannot do a sim swap. This is an issue that had previously been "resolved" but clearly has not. I use that number up until the time that it was ******. Of course now no one knows what the issue is as all of my payments reflect as a credit on my account but is not being deducted from the amount owing.

I am at my wits end as I have been without my number which I have had for almost 20 years for nearly a week. I lost all of my contacts as I cannot get whatsapp activated, I am losing potential business as customers aren't able to get a hold of me. I am unable to access my banking and investment profiles because the otp's get sent to that number. My kid's schools cannot even get a hold of me in the case of an emergency.

I escalated to the complaints, customer service and legal teams but NOTHING has been done apart from an automated response.
