There is a large pinned post on the first page of this Help forum you just posted on "Contact Airbnb" which has phone numbers and all the ways to reach Airbnb.
But you should be aware that basically no one is receiving any sort of priority support right now- their customer service dept. is in total disarray.
@Simon22 The difficulty of finding the contacts is by design. "Priority support" is fictional, just like many other terms in Airbnb parlance such as "security deposit" and "dedicated team." Adjust your expectations accordingly.
