Wasting my time

I closed my business bank account I think almost two weeks ago. The lady I spoke to on the phone confirmed that once the settlement amount of R181. ?? was paid the account will be closed. Also the account is not showing anymore after that on my online banking when I log in which shows it must be closed but still I receive a message this morning that my account is in excess abd i must make a deposit. I want to make it clear that i paid the settlement amount as instructed and I find this wasting of my time very annoying. Fnb you can go to hell I closed this account with you. And i will just ignore all other messages in connection with this.
