No payment - No assistance and No help!

BOOKING.COM is the worst company to advertise your establishment with! Beware - they do NOT pay their outstanding payments! I was the owner of a establishment that advertised on booking.com and after I sold my business I am still waiting for my final payout from them - a year on! They have one excuse after another and even though I have handed them over I have no response and as they are listed in the Netherlands I have NO recourse! They owe me a lot of money and I get NO HELP from them!
