In our 2.5 years of hosting, and keeping superhosts status all this time, we've been treated sometimes gracefully by Airbnb's Customer Support, and sometimes with total disdain.
It depends on the nature of the case, on who's in put in charge on their side.
From our experience, if you want to be rightfully compensated, either from damage deposit or from host guarantee, you have to fight real hard.
Even if you have evidences to support your claim, you'll probably have to explain your story 2-3-4-5 times, resubmit your documents, to different staff, different departments, etc.
After hosting our worst guest until now, we spent 2 weeks fighting to claim our rights. TWO WEEKS.
It means spending all this time because of a very uneducated/dirty/dishonest/rude/etc. guest. Losing so much time on the last person you'd like to deal with on earth is an indescribable nightmare.
It demands perseverance and you have to be ready for that, even if the guest behaviour's brought you to tears. Initially, Airbnb will give as much credit, or more, to the guest than to you.
When they see that the guest is unresponsive to all their messages or calls, they may start treating you respectfully. It depends on you also, on how much of your time you're ready to lose.
