Hey there. Sorry about that - we send people invoices via Bank of America and Chase, but sometimes they act up and stuff doesn't get sent out or gets delayed, and we have to re-send the invoice. (We're working on a better system now, hope to have that done by next week.) Could you send us your order number? We can probably just re-send the invoice if something went wrong the first time.
Cool, that's what you called service.
