Account still suspended even after all invoices had been paid

We have been emailing Booking.com constantly for a month for them to re-open our account. Invoices have been fully paid and they are still flagged in red. This is high season for our business and this lack of responsiveness from Booking is really hurting us. Customer support can not really help. At this point, our small business is at Booking's mercy. We wish we can have someone to talk to and understand how long we still need to wait. Or if there are additional payment confirmation required. Does anyone know a number we can call or a way a chat can be open with someone in Finance to get the problem fix? 

Found this channel to see if anyone can reply to our query. Thank you very much.
