FICA Failure

I have received the worst service / non assistance from FNB. I am required to FICA my account, I've gone to the Blue Route branch stood in a queue and when getting to the front of the queue was asked for my proof of address and ID. I had with me an Affidavit as well as my landlords account statement which he masked the figures and was told that they cannot accept that as it is non compliant. I was not provided with an alternative as this was already a mission to obtain.

I would like to know why I am being discriminated against been a single mother and am not able to just get off work to go and stand in queues at the bank especially with Covid and tomorrow been pay day. Is this going to take weeks to resolve? How am I going to pay Rent and feed my children?

Please advise as my landlord refuses to unmask the statement.
