@Christian2756 A google search actually calls up phone numbers for Airbnb. They don't make their contact info easy to find, though. I've never had a hard time calling, but I haven't had to contact them for a long time and they seem to be getting more difficult according to all reports. (I don't have the US number at hand, or I'd give it to you)
Unless it's some emergency situation, a lot of hosts find it better to message them, though, or contact them through their Twitter account. You then at least have a paper trail of interaction about issues. And if you call and they say they'll call you back, you could die of old age waiting for that promised call back.
Most of the customer service reps are ill trained, don't even know Airrbnb policy, give out incorrect or incomplete info and seem to require multiple back and forths to even grasp the issue you have contacted them about. You'll get much better advice and help from other hosts on this and other hosting forums, so unless it's something that only CS can deal with, try asking your questions here first.
