Citibank to Mark ... oh yeah, Well eat this!

Apparently my naive brain thought by paying off the balance it was done ... no, it's not. They informed me of "interest" accrued up until that point would have to be paid. The email they sent was not nice about it. BTW, my email closing it wasn't me telling them to fuck off either. I simply asked to close it now that I have paid the balance. I hate the credit card industry. They are so fucking evil.
