Who knows how to transfer a SIM to the owner's account?

My wife and I have been messed around a bit much in an effort to have her SIM transferred from my account from which her contract is paid to her account. First I tried to have this done, telephonically then I tried in the branch, then they said she had to go in to a branch and have it done, then she was told all sorts stuff like she needed a new sim or had to go to a police station, etc. I drove in to try and sort it out with both of us there but they had just closed and wouldn't let me in and there I was trying to talk to my wife through the closed door. Please can someone from FNB Connect who actually knows the ins and outs of this contact me so we can sort this out without any further you-know-what.
