FNB credit card division, very poor service

I app**** for an increase in my credit card because a message popped up to say I qualify for an increase on my FNB app. I app****, a quote came up which I accepted, I also activated the Debi check authorisation. 48 hours later only when I query it with a chat bot agent named Roshta do I get told that I need to send through an IT34 assessment, an IRP 5 assessment, last 3 months payslip, then they don't accept income from investments but only income from retirement annuity, such nonsense and poor customer service, going to switch banks and have no dealings with FNB
