Refusal to give bank statements

I went to the branch to request my bank statements at 5/11/15. I requested for bank statements to submit to SEFA however the teller refused to assist saying I should go to a credit consultant who will assess my credit score. I refused because she was harassing me to undergo a process I view unnecessary since I didn't want FNB and the staff at SEFA have their own processing to assess applicants and don't need FNB's assessment only bank statements. You can't refuse me statements that I'm entitled to that I will be paying for. Your customer service stinks
