Closing account

I tried to close my account at Bluff Durban branch. I do not have proper fingerprints. 30 or more tries later I asked if perhaps the manager could override it. I was told" It not our fault . It is your fault. You do not have fingerprints." I was then given a form to fill in. No where does it give a closing date. Assistant said she would email it and wrote an email address on form. Not being sure that it was done. I tried myself. That email pus 2 others on form . Mail failed. Then I tried online. Not available now. Closed. No success there either. A communications company. I am worried about this because I continually hear stories about enclosed accounts that generate huge amounts which I cannot pay.
