As a host, I cannot know how much AiRBnB and their bank will take from my money, I got 40% less than expected!

AirBnB simply cheated me and after all didn’t answered on my questions, I as a host still don’t know how much money I will get after guests left. AirBnB payment option is not reliable so I had to double the price.. and still don’t know how much my payment will be.  It’s funny how much time I have lost asking AiRBnB to solve this problem.  Imagine, you want to rent a flat and don’t know how much money you will get after commission of AirBnB and his intermediary banks.  I sent all proofs and papers from my bank (my bank takes only 2 euro) to AiRBnB, and still have no answer.  This is bad, very bad experience with this site, for my first (and probably last) renting I got almost 40% less money then expected… and still without proper answer..  Be careful of their “pleasant, sweet word mails” without solving problems.
