When I reviewed my credit card statement yesterday I found an unexpected charge from you. Before you automatically bill my credit card (5 days ahead of the bill date) it would be good business practice to send me an email notice. I get one about every email I send, so you're obviously set up to do this. But for this most important one, nothing. Other companies I deal with send a notice a week or two before the payment date saying "Your account will be billed $xx on (date)."
