What are my options for dealing with a homeowners insurance company I believe is acting in bad faith?

We filed our initial claim on November 20, 2010. We complied immediately with all requests for information. Beginning January 3, 2011, our agent has repeatedly told us that the check will be going out next week. Every week it's the same story. The personal property claim was very cut and dry. They have no dispute as to whether the items claimed are covered (per his own admission). What would be the best course of action at this point? I live in California. File an RFA? File a complaint with the Insurance Commissioner? Hire a lawyer? I'm looking for the best way to quickly recoup our losses since we had to pay for much of the construction/repairs on credit. Thanks!!
