So I walk into FNB to change my email address, and the consultant immediately asked me if I would like to convert to Fusion it's a better account and whot not. In the end I converted. However, he said when I receive my salary I should move it out completely out of the fusion account - and within 30 days move it back. I don't understand why. They will charge interest on a negative balance if I move all the money out. Or do I understand this wrong?
