How do I dispute a charge on my statement?

To dispute a charge on your billing statement, please send us complete information describing the disputed charge. Please include the merchant’s name, the date of the charge, the month the charge was billed, the amount of the charge, and the reason for the dispute. If the item was returned, please tell us how, when, and where it was returned.
