Greg Levine Alltrades Home Improvement - Home improvement scam

We hired Greg Levine to perform some drywall and stucco repair after getting his contact information from an online contractor referral site. He performed the repairs well, so we hired him, and prepaid him, to install a French door to replace our sliding glass patio door. After cashing our check he has stopped answering the phone or returning calls. He presents himself as a licensed contractor, but subsequent research revealed that his contractor license was revoked in October 2005. He has apparently been illegally operating as an unlicensed contractor for years under a variety of different company names, such as Greg's Home Improvement.
