OK, this doesn't surprise me too much. Title companies who fail to send title policies to their customers fry my brains.
Take a look at the HUD-1 Settlement Statement. You should have received this form at the closing. Look at the back page in the 1100 section. You should see the name of a title insurance company somewhere there and hopefully it isn't just the name of the agency. Google the title company and explain your predicament. If you can't find a name or get no satisfaction, contact your state insurance regulator for assistance.
Consumers should beware. If you aren 't getting a copy of the title commitment before you close, there's a good chance you are dealing with a sloppy title agent. The problem with sloppy title agents is that they may never actually issue you a title policy and they just MIGHT go out of business before you figure that one out.
