MTN account - 5 month still no feedback!!!!

This is the worst experience that I have ever had in my life. I have been trying to sort out my account with MTN since last year November 2020. But still today no one has contacted me. I have email trails as proof + Voice recordings + screenshots of how may times I have called and how long I have been put on hold. I have even contacted the legal department to get advise and they sent me another clients personal information, and as an employee of Fidelity ADT in the accounts department, I am fully aware of the POPI act, and it is ******* to send out personal information about any client - or even just leave your laptop open with personal information on display. But not just that - I have been begging for someone to sort out my account and it has been month and still no feedback. I have been going into the store to get advice and they just keep on giving me someone else's email to try.

Please help me, what should I do?
