error in expense reports

[mattlarsen]

i have an expense that hit both my August and September statements as two different charges.  how do i fix this?

@mattlarsen does that mean you were charged twice for the same expense? If so, then you need to contest the incorrect charge and have the card issuer credit back your account. You will see a negative amount card charge come into your Available Expenses. Once it comes in, add the refund and the incorrect charge to the same report so they will zero each other out. For now, submit the correct charge.

kevin, thank you for getting back to me.  more clarification is request though.  First, how/who do i contest this with.  Second when you say "have the card issuer" do you mean American Express?
