I was told by the first tech that someone else would be coming after him within 30 minutes and to leave the crawl space door open so she would see it open and check in there. I immediately went to the crawl space and opened the door and went in. I stayed in there for about 20 minutes and no one ever came. There was a card on the front door that said they were sorry they missed me. I didn't know if that was from the person that came first or the one that was supposed to come second.
