Dont expect more than what theyve promised. With nine listings you're doing very well for yourself. Consider the glass half full.
What exactly is it that you are wanting AirBnB to do for you? Did you want them to side with you when you had a problem with a guest? How much did you lose and is it worth the effort of calling them when you can make that money up with the next few guests. Increase the rate a few dollars over your 9 listings and poof! you have made the money back. Are you wanting them to send you an award for doing what you signed up for? They've awarded you superhost. They wont list you as AirBnB plus? So what! Does AirBnB Plus allow you more exposure for your properties outside of AirBnB? I dont think so. If your places are so busy that even Airbnb wont consider them then either adjust to fit the Airbnb Plus metrics or keep doing the stellar job you've been doing.
I'm just playing devils advocate because your glass is very much half full.
