I'd call it day. The band is obviously not serious about recording, despite what they might say. Just go home. If the band calls asking where you're at, say something along the lines of: "Well you guys weren't here and you didn't call so I made plans. Maybe we can reschedule in a couple weeks..."
When they call in a couple weeks, tell them you're booked solid. These are the kind of people you DON'T want to work with.
