FNB Disregards their Clients.

I laid a complaint about two months ago on this platform and FNB still has not resolved my issue. they gave me a reference number ***NF and proceeded to give me the run around. each person I engage with needs an explanation of my complaint. they assumed because I am silent that the problem would go away. I have been with this bank since 19 October 2004 and the level of disregard I'm seeing lately is appalling. I have not received a clear reason why my accounts were handled in the way they were and no one has followed up on my query.
