Simswap unsuccesful

At the end of July 2015, I contacted call center to do a simswap because I wanted to change to a micro sim. They asked me for 5 numbers dialled within the last 3 months and the airtime amount loaded last. I gave the 5 numbers as I was looking at them straight from my phone, and the airtime. But they told me that it was declined and that I must go to a branch. I went to Vaal Mall, they asked for the same questions and I read those number straight from my phone infront of the *********** guy helping me. I even showed him My ID book and proof of residence to prove that the simcard belongs to me, but he still told me that the system is refusing and there is nothing he can do. He said I must buy a new simcard and have a new number. He couldn't care less, why did the call centre refer me to a branch if the branch will tell me the same nonsense they told me? My information was accurate as it was coming straight from the simcard in question. I had to suffer because of your stupid system that doesn't work properly! *********** employees will bring your business down!!! #****ed off!
