They call my cell and never leave a message. My cell is an older 3GS iphone and there is no blocking for it. So they will call until they get tired because they will never get an answer other than the basic message.
Same callers as "Arghhhh!" Caller with a foreign accent claimed to be from Carlson or Carlton Roofing and were going to be in the area to inspect roofs after "the recent storms". Don't fall for their pitch. They'll always find some "damage" to repair and if they don't find some they'll cause some and then claim it was from a storm. Then they'll rip you off for the repairs.
