How can I reach someone in management at AirBNB?

[Eleanor87]

I have had an open ticket with Airbnb since mid-December. I call every week and I still don't have a resolution. They have sent my ticket to Regulation & Tax and they won't respond to me. Customer service has contacted Regulation & Tax every time I've called and asked them to contact me and they never have. I want a resolution, so I think I need to reach someone in upper management. 

Thanks for any help you can give me.
