FNB unprofessional

I opened a business account about 2 months ago and activated it. For the past 2 months it's been deducting basic bank charges and on Friday last week the I got an actual deposit into the account. When I tried using the account I was told the account has a hold because of a proof of address issue. I don't understand this because I submitted my very current lease when I was opening the account, also, why was I not contacted when they had this issue and just went to putting a hold on the account?

I emailed my lease again on Monday and was told (via phone call) that their turn around is 2-3 days. I called again on Wednesday and was told my issue hasn't yet been resolved. I called on Thursday morning and was told my issue was now escalated to the managers.

Today (Thursday) I went to FNB in Tableview and was welcomed by a very rude man who gave me my ticket. The consultant made the same call I have been making and was told again that the matter was escalated to the managers. I had no choice but to leave, without any kind of help.

It's now 5 days with money in my account that I cannot use. Why was I not emailed or called to be informed that my account had a hold? Why were the funds able to get into the account if the account is not functional? Why was I charged banking fees if the account was not functional? Why was that front of office guy at Bayside Mall FNB rude?
