Booking is not paying me !!!!

I'm new to booking but not to the hospitality business as my b&b is 30 years old. I joined Booking and my property is 100% fit. I received my first booking, payment is done, guest receive by us and booking is 

holding my money until I don't have other bookings. 

I just closed my B&B for further bookings in this site as what they are doing is abusive and rather illegal because that is my money not their so they broke the trust and I won't allow anyone else to pay to booking our share. 

I only received a reply of robot answers so is here any partner that can help me to get to a complain number in this company, please. Thank you

Kind regards.
