Dissapointed as a client to MTN

I went to do an eSim at MTN Kiosk Central City, Mabopane and asked a consultant called Thabang to help me migrate to eSim and asked me if I was on contract or prepaid. I explained that it was a prepaid SIM. Everything changed i was told that I must go do it online. Their preference is contract clients whom they can help migrate to eSIM. When we buy Data and Airtime, MTN does not discriminate against our money, only when we need help, and I have been an MTN client for many, many years with two sim cards.
