Invoice for Jan 2020 per email

I normally receive an invoice per email but not for Jan 2020 up till now


Isle of Wight …

I received a couple of invoices by email yesterday, saying payment due by 16th

However, I use Payments by Booking.com - guest pays at the time of booking, then Booking.com deduct their fees and transfer the balance to our bank account - so the invoices have already been paid ....
