I just spent a splendid two weeks trying to get through to Airbnb support. I have received robot messages from several mythological support people. Some are insulting, some claim to be supportive and not do anything, and none seem to read the messages I sent. Yesterday they added another fun category of pretending to call me back and claiming there was no answer.
I think even a robot could see that the messages were being sent from my phone that was in my hands. I have blocked all my time with Airbnb and plan on finding a company with actual people in it to take my money for use of the website. They charge nearly as much is a reputable rental agency and give nothing in return.
