Yeah, that's what happened to me. I booked through expedia, and missed a flight (no fault of my own). The airline outright refused to deal with me, saying I needed to contact expedia to contact them. Half a day later, I still hadn't been able to hear anything useful from expedia and getting desperate ended up booking a new flight out of pocket (and never got compensation either).
I've since sworn to only ever book the flight directly from the airline.
