Sim Swap

I called the Customer service to do a Sim Swap and was asked Highly Impossible questions to answer. How am I supposed to remember the last number that I called in the past week and how much recharge I put in. After the trauma that I went to, I do not think anyone will be able to remember that.<br> It is an Inconvenience for me to go to a Cell C store to do the Sim Swap as 1. it will be a cost to me, 2. have to wait in queues to be helped.<br> Not happy with this Policy.
