Unprofessional

I opened a account for my son last year at fnb and we activate it this year, but after a long struggle as my son is a 1st year student there wass no money coming in. Today he received his allowance and we found out that his account is closed. He went to the bank and the staff was very unprofessional. The didn't even asked him if they can assist opening a ne account. and im to far to help him. FNB I thought you were a better option but it seems not.
