sim swap

I am disappointed with MTN. I tried to do a Sim swap. I gave them 3 frequent dial numbers, last time I used the phone and phone model. I could not answer 2 questions as I forgot the last recharge amount and subscribe plan. I told them that the last time I recharge is when I used the loyalty plan, but the consultant told me that she could not see the loyalty point on her screen MTN needs to simplify the process of Sim swap for prepaid customers just like they do for postpaid customers. They can link the number to my ID
