Access to my new hotel

Good evening,

I'm the new General Manager at the Hotel Northland Green Bay and need access to my hotels account.  I've tried searching the booking.com site without luck.  I don't believe anyone left on property has admin rights to the account.  Could someone please assist>?

My email is mbryan@hotelnorthlandgreenbay.com and direct line is 920-393-6099 whatever works best.
