Closed/ Not bookable

 We have 98 accomodations and conection over avantio.

We see that in booking.com almost 30 accomodations are closed/not bookable.

Booking does not have an answer and sent us to avantio, they cannot connect because the accomodations are closed in booking. We do not know wht and there is nobody who can help us until now.

Anyone knows what to do??????

Thank you
