Online Banking messages completely ignored !!!!!!

My daughter tried to close her FNB accounts at the Sandton branch she was dealt with by a very rude consultant that just took her bank card and broke it up in front of her and then said he required documentation from her. She then gets a demanding sms from FNB to say that if she doesn't pay R17.40 into her account by the 02/11/15 further action will be taken. I then went into her account last week and the amount was now sitting on R34 ??? I transferred the R34 into her account her balances are now sitting on zero, i have sent numerous messages requesting they close the accounts as my daughter is now overseas but i just don't get responses. I will NOT pay any more money for debits you put against these accounts !!! Im tired of FNB demanding then adding on more and more charges but do not action my request!
