FNB Incompetency

I rejoined FNB last year 2014 November, verified my address & Proof of ID then I used my moms documents to Verify Proof of Address as I don't have anything billed to my name. This year two months back I went to the Rosebank Branch, the guy told me my account is at risk of being frozen as they do not have any proof of ID & Address from me this was a shock. I explained to the guy that the only thing I have in my name are letters from school, he said an invoice from school will work. I Requested an invoice from school which unfortunately on 14.10.15 my account was frozen. I went to Balfour & the guy told me he couldn't use an Invoice from Uni. I spent an hour explaining my situation, eventually went to Woodmead with a friend and verified these docs, they assured me my account was ok & I can start using it. My card till this day does not work and being the only account I have I am so disgusted by the level of incompetency. One to another employee cannot get one thing right, from the one who opened my account. FNB is making life so difficult for me as I have to call or go there daily. What do I have to do to have my account active again seeing I've done everything! This is unacceptable
