Standard bank account closure problems

<p>I closed my standard bank account, money market account, on the weekend. I was aptly paid the money owed to me and the paperwork needed was done. Today I get a message that states I have a negative balance and I have withdraw a sum of money. Really! How can I owe money on an account that is closed? not forgetting that money had to be paid to me before the account was closed. Is this now going to be a saga of me having to take time off work or waste my weekends at a branch trying to solve this! You always think that won't happen to me until it does. </p>
