They allocate 24 hours for the property owner to accept an offer. During that whole time, even if the property owner has accepted, they continue to show a "So and so has HH: MM: SS to accept your offer" on the Messages page, which to me is a statement that they have not yet accepted my offer. Yet apparently it was accepted and my card was charged (I used their supposedly secure payment system). I never received an email at the end of the 24 hours (and yes I checked my spam folder). This led me to think that the offer fell through and I booked elsewhere (directly w/ the owner). Then 8 hours later my credit card was charged. Great, now I'm double booked. Still no message and their support says it takes them 2-3 days to respond. The property owner didn't seem to understand the system either so I think the interface on that end must be just as bad.
