No shows in SoCal league...

Have some friends with younger players, for the 2nd time out of (3) weeks they txt me this morning saying referees are a no-show again and what they should do?

I tell them to call to see what the deal is, but nobody is around so is there a way to check to see what crew is assigned or not? Hotline for problems? Shame the kids and parents spending the time and effort only to not play due to no shows.

Any suggestions are welcome.
