Wrong advice about account closure

I opened a FNB account, the account did not meet my needs and I went to close the account. I did not know I had to come on the day that was suggested and went a day afterwards. I was then told I need not come back I should leave the account and it will close automatically. I phoned and was told my query will be send to the correct department. I was then emailed stating that they will assist me and the I should ensure that x amount was paid to the account to settle. My initial complain stated I will not be paying and outstanding fees as I was ill advises by the banking official. The bank should write of the fees and send me a closure sms and email.
