For one of my accounts that I was closing, a penny ($0.01) interest payment was credited. Rather than issue a check or conficating my cash (LOL), they sent it to the government as a tax payment.
I still laugh about this. I'm expecting a piece of paper saying I've paid $0.01 for tax. The stamp is going to cost them so much more than this.
The account is closed. Ask them to credit it to your credit card as a payment, when you want to deal with it.
