How to contact airbnb?

[Floh0]

How is it possible to contact airbnb? I have some technical issues with several disappearing 5-star ratings. But I cannot contact airbnb.

It says, that superhosts can get priority telephone support, but still, no phone number is provided.

I tried to use a phone number from a previous communication, but when asked by the automatic reply to enter my phone number, this phone number is not accepted to some technical reasons.
