Looks like the OPs cancellation was the fault of United, see comment section
http://www.flyertalk.com/articles/ne...l-flights.html. In this case 10,000 miles is woefully insufficient and compensation for accommodations is due, unless like others have said, the OP lives in the LA area.
In any event, even if not bound by the CoC, United should do what it can to make the best of a bad situation. That's customer service 101.
