You are right, this is misleading and actually downright dishonest. Why does it say priority placement in search, when on these forums, Airbnb has confirmed that Superhost status has no effect on your search placement? Having a Superhost filter is not the same as priority placement in search as most guests have no idea about it so will never use that filter.
As for contacting Airbnb, I use a UK number as I am based in London. I have never had a separate Superhost number to my knowledge. Before being a Superhost, I would call the number and be put through to a call centre in Ireland. Now, once I plug in my details, I get a message like "Welcome Superhost!" and am diverted to a call centre somewhere in the US. Either way, I have always got through very quickly.
However, from comments I've seen on the forums, this is not the case in every country. It seems that it's much harder to get through in the US for example than it is here.
Also, you are right that it is frustratingly difficult to find the contact numbers on the website. Yes, they are here on the forums, but that is not good enough. People shouldn't have to hunt around for ages looking for the contacts and many people would not know to go to the forums looking for them. It's a deliberate strategy to cut down the number of people who call Airbnb CS.
Frustrating as all of this is, I don't think any of it should lead one to believe it is a scam and that Airbnb is going to run off with our money!
I share your disappointment that Superhosts are not adequately promoted/rewarded (I also used to think I would get a higher search placement when I first achieved the status), but I try now not to stress as much about it. I'm happy to receive the badge and I use it as a selling point on my listings and profile.
It would be great though if Airbnb did a better job of educating guests about Superhosts so that more of them would actually use the filter in their searches.
