FNB a nightmare: 3 different people 3 different instructions

Communicating with FNB is like an episode of Monty Python. I went to FNB chat as I had a complaint re: Forex not responding to a query 2 weeks ago, Online chat said cant help me I need to verify my new laptop on premier helpline. Called these people, Motel said she cant help me so transferred me Maripeng at internet banking who said she cant help me but my new device will be automatically verified when I log on. So WHO do I believe???
