FNB is not helpful

I want to complain about the terrible service my husband has received from FNB. As it stands, he has zero access to his accounts. He cannot login to the app even though the technician's say everything is fine now. All devices were blocked without him knowing. So we had that unblocked but it's taking days to resolve. And still no access. Consultants say the app will be available in a few hours but that never happens. Payments he made over 2 weeks ago still haven't reflected into any accounts. The account he has turns out they opened an invest account and not a transactional account. Upon finding that out he opens a transactional account but he still doesn't have cards or access to the app. Its been more than week. We cannot buy food because FNB has locked up our money. And technicians keep saying it's all sorted and consultants say cards will be here tomorrow but its all lies because we still have no access. Communication is poor. Its now Christmas and we can't do anything because FNB is keeping our money.
