SIM not working - No support from MTN

I recently (5 April 2023) went in to a MTN store to convert my physical SIM to an eSIM. The gentleman behind the counter assisted me with the process and as soon as my physical deactivated, they said I should receive a QR on email that I need to scan and follow the instructions. The QR code only came through later that afternoon, only to be 'no longer valid'. I went back to the MTN store 3 times for assistance only to be told that they will not be able to assist me because of the system that's not able to close the open order against my name. I have contacted the MTN 'service champions' LOL on 135 and they as well are not able to assist me. I have mailed the customer and complaints email and guess what, no response. I am currently talking to an agent on MTN's Facebook page but they have also not resolved any issues since last week. I am now sitting with a deactivated SIM since 5 April 2023 and can't even do my banking because I can't receive OTPs on my phone.
