MTN 135 centre and branch incompetence to activate an eSim

I’ve been trying to change my contract simcard to a eSim for the past 3 days and still I can’t get help from the branch and telephonically. For the past two days, I haven’t had any network since my simcard has been converted to eSim and yet the eSim activation QR code doesn’t go through my device it states I should call my carrier which I did and I can’t be assisted. I’ve been with the 135 customer line for more then 3hours and they keep throwing me around, from department to department(Activations, Customer Care, Prepaid department ect)
