Hi, A nice family recently stayed at our house, and the experience for both of us was positive. I left the guest a five-star review, but she did not complete her own review. I sent her a quick email to encourage her to do so. She wrote back and said she had written four reviews but due to a glitch in the airbnb system, she could not complete. (When she hit the continue button, it all went south, every time). This is the third time I have heard from a guest that they wanted to give us a positive review, but the airbnb system failed them. (Or at least they believe the airbnb system was at fault. There's no telling whether there was some sort of other technical issue at work). In any event, none of the guests, nor I, have been able to figure out how to contact airbnb to get resolution. Is there a way to do this? I can't figure out where to send a help message. Thanks.
