I called 2 nights ago and the rep said tech support would get my problem ticket in two days. Tonight I had someone inquire and so lost that guest, because the pricing is still not fixed, ugh!
For the phone number : Google Airbnb customer service number.
Among your search results (scroll down) and you will see bold customer service numbers, and one is toll free. I think calling in day might be a better option , not sure what hours tech support is staffed for major issues. Good Luck!
