@Gianni250 I haven't had to contact support for quite awhile, and I understand that it has really fallen off a cliff lately.
In the past, when I get answers which don't address my issue and which the CS rep doesn't seem to understand, I have replied like "Hi, Xx, Thank you for your response, and I appreciate that you are trying to help, but the answers you have given indicate that you aren't understanding what my issue is. Could you kindly pass my issue on to a supervisor, who may better understand the problem and how to solve it?
Thanks for your attention."
Lots of politeness, and a direct request to have it escalated has worked for me. YMMV.
Also, contacting Airbnb through their Twitter account is said to yield the best results, and phoning seems to be the worst way.
