Easy Account closure

I am very disappointed because, I have two accounts with FNB I wanted to close the Easy Account because I can't afford bank charges on an account I'm not using anymore, so I called the bank but the call centre lady said I can only close an account at the branch, then last week I did go into the branch the lady tried to help me but she said the system was blocking her because the account was not opened at their branch, so her supervisor had to override the system but she still failed to get the account closed as well, then I was told the matter would be escalated but now it's been over a week and this account is still open and FNB is taking bank charges from it.
