Very poor service FIRST NATIONAL BANK

FNBREF#***. it has been over 25 days (3weeks) of not getting any response from FNB,the debit has went off in my account and there is no funds in my account. The interest is going up and no response from FNB on my claim. I have been paying insurance but seems like FNB does not care and does not want help since I am unemployed.. very poor service.
