Billing me for a closed account

I am still receiving statements from my blue bean credit card which was settle and closed on 9 September 2015.<br> When i called the call center to find out what was happening, i was told that the account was never settled and rent and monthly fees have been adding up. When i closed this account on the 9th, i was told by the operator that the amount was settled and the account is closed, there after i was told to destroy the card, which was done. Now i have to go to a branch and pay the amount on the statement and then call the center again to close the account.<br> <br> I find this unexceptionable that i must pay for someones mistake. <br> <br>
