BAD SERVICE WANT MY ACCOUNT CLOSED

Good day. Im a very unhappy customer. I went to FNB Rustenburg Square in Rustenburg to change my account number because I suspect that there going to be ***** commited on it and then wanted to open a new account after about 5 minutes the consultant told me my account wont be closed unless I paid an amount in arrears when I asked him what amount he got very rude and told me he don't know just pay it so I can close it! I mean how rude is that. I wanted to know why there was an amount due because there was just money in there why do they want more again his reply was I don't know so I asked him to please get someone who knows how to do their job because clearly he cant its just I don't know with him. When I opened this account 2 months ago I told them to deduct the bank fees on the 25th of every month now they deducted it on the 10th of November 2017 why did they do that? Now they say its my November bank fees how can they deduct my bankfees on the 10th when I pay on the 25th of every month they did deduct the previous month on the 26th so why must I be responsible for paying that fees when they try to take it when I don't pay that's not what was agreed upon when I opened the account. Im sorry but after that bad service I refuse to pay that amount because they deducted it on the wrong date not me I want my account closed and who ever made the deduction go off on the 10th must be held responsible for paying it. If this account is not closed I will go to the Ombitsman. The threats made towards me from the staff of FNB Rustenburg Square for putting me on ITC if not paying I will also take further because it was agreed upon that the bankfees must go of on the 25th of each month. Please close my account I will go somewhere else thank you.
