Maybe that could be made more clear on the listings, but it should certainly have been made clear when the invoice was sent. I would not pay part of an invoice that I thought was wrong, I would want to sort out the misunderstanding prior to making any payment. A polite exchange should be all that is needed with both sides admitting to a little of the confusion and misunderstanding.
