Welcome to the Q&A Forum

Hi there! Unfortunately, from my experience I've found that if you purchase a listing that does not have the correct GMB profile AND Facebook page selected, it's impossible to get Moz to recognize the correct page. Location details in Moz Local will be pushed to Facebook, but not the other way around—so if the listing you purchased is pulling the wrong page from the start, it seems like it's stuck that way. You could try emailing help@moz.com to see if there is a way for them to manually switch this out for you.
