Call was from one of those annoying home improvement/home repair companies. I don't do business with phone solicitors. I was polite to the person that called and said I wasn't interested and she was equally polite in saying thank you and goodbye.

called the number back, a recording stating that the number has been disconnected. They have been calling for  a couple days, never leave message. Orange County: Buena Park, Anaheim, Fullerton. no idea who they are.

calls all the time but never responds or leaves a message

Has called continuously but doesn't leave message.
