Non-payments from BOOKING.COM

I have had some issues with booking.com due to an error with my listings (something I didn't know).  Booking.com still sends customers, but since July 4th, I'm not paid for these reservations.  Anyone else with this problem ?  It's now more than 2000 euro and I can't pay my bill for gas anymore :-(

All my previous requests has failed.  I'm now refusing the guests to enter my building.
