My credit card statement from US Bank, XXXX. XXXX XXXX, XXXX XXXX, MO XXXX, showed a balance due of {$770.00}. I transposed, in error, the cents and remitted {$770.00}, a difference of XXXX cents. For this slight error they billed me for {$8.00} in interest. That 's XXXX times the shortfall and it seems ludicrous to me. I called their customer service phone number as I did n't realized that I had transposed the cents and they explained the {$8.00} interest charge was a result of of XXXX cent error, and made no effort to resolve what I thought was an extraordinary interest charge.
