I had a whole bunch of gift card shenanigans going on yesterday. I won’t go into the details, mainly because I don’t know what exactly the problem was (and neither did the people that I spoke with on the phone from Airbnb).
Anyway, long story short, I needed to contact Airbnb. Usually not too bad, but in this case it was much easier said than done. I finally ended getting in through Twitter by chatting with @airbnbhelp. They got me in contact with a case specialist via email, and he eventually had to call me. It just so happens that if you call the number back that he called from you get connected to someone from their Trip Experience Team. My issue eventually got resolved and I now have the Airbnb contact phone number in my contact list if I ever need them again.
