Complaint Resolution takes to Long

My account is in a negative for no reason FNB has been Promising to fix this from the 17th of July 2015. The first time I called I spoke to the fist consultant on the 17th of July the second time I spoke to the second consultant on the 27th of July, the 3rd time I spoke to the third consultant (Premier Banking) on the 3rd of August but still has not been fix. I have completed all the necessary forms and I have resent them to FNB. This morning August 7, 2015 I call the complaints department and they could not assist me they only refer me to Premier Banking again, and they still expect me to pay the monthly banking fees even if the account is not in use or fixed.
