Hi there. I booked this room recent

Hi there. I booked this room recently and have just received an invoice. The booking information says that it can be cancelled up to 14 Dec 2016, so I should not have received an invoice now. I plan to pay at the hotel on arrival. I think that an error has been made, or maybe this email is not from you.
Please confirm that Booking.com only take money on 14 Dec 2016 and that I can pay the balance on arrival.
Thanks
