Bad customer service

I paid cell contract in full and I requested fnb to port me back to Vodacom. They promised me that it will be done in 24 hours and I must go to the branch for sim card. I went to the branch yesterday and when I called them they say my sim card was registered under sim swap. They said I must go back to the branch again. I went to the branch today and it took me 1 hour and my matter is still unresolved. I spoke to Mbeki who was rude. Florence had a conflicting opinion with Norman and Pamela dropped the phone. FNB new loggo is How can we frustrate you I am really frustrated. FNB is really frustrating people. FNB is only good in deducting money.
