MTN eSIM Services and Customer Care are Clueless and Shocking

Good day

Ive been a loyal MTN customer now since 1999. I have recently upgraded my phone to a new Iphone 12 mini with a Iwatch. I was told by the Istore to activate the eSim through the MTN store. The MTN store told me to phone the call center. The call center told me to go to the MTN store. I was told that I am on the old system and I can not have an active eSim... How would MTN then sell me a eSIM device if I can not use it... I have now brought an Iwatch that has no use to me. I have logged multiple calls, chatted to 12 advisors and technical ppl at MTN without ant results. I have been to 3 stores and everyone just shrugs their shoulders and cant help me... I am thinking of going to the Consumer Ombudsman if I cant get my eSIM sorted within the next 3 days, surely it cant be that difficult. I have received so much back and forth instructions I do not know now what to do any more, and I feel I have brought the watch under flase advertising as I can not use it as per advertised to make calls... I need someone to urgently sort out this matter
