Mtn caltorn centre

I have had the most horrible horrible customer service experience of my life, so a few weeks ago, i did an e-sim at MTN in limpopo, and since then my sim is not working, I relocated to Gauten and went to mtn - caltorn centre, they said they are offline, which is understandable, I went back today and wow, the lady had no interest in assisting me, she was busy on a phone when i arrived and her facial expression alone could tell that I am disturbing her, she said “you must go back to limpopo and get assistance there since we are not the ones that did?????whaaaat?? I then told her that it just says i need to rica it, she asked for my number and said no its ricad, I then called mtn so that she can hear that it says i need to rica it, she continued doing whatever she wS doing on her cellphone, she then said” personally i dont like assisting with esim, i turn people who want an esim away because it never works, she said i must go on my settings and do it there????so my question is why would MTN advertise that we can come and do an esim just to get such ??? My number is not working and I am not getting assistance
