commissions & taxs payout

I am a host. I recieved invoice of commission and taxs by Booking.com. I am unable to trasfer the payout to booking.com. I don't know whether I have a direct debiot as it is not visible. Today is my last day to make payment and I don't want to be in the catagory of late payment. I am trying to contact booking.com for istance but unable to send message.
