On our business line. No Caller ID, just the number. Caller did not ID themselves. I answer identifying our business, she was talking to someone else (could hear multiple people talking in the back). She stopped, as if she was surprised someone answered, asked, 'Is this (our business name)?" "Yes,it is." "Are you still located at ....?" (Which she used our home address, not our business address). "No". "No? You're no longer located at ....?" "Who is this?" "This us the Chamber of Commerce and we are updating our records. What is your current location?" "We will finish this later, good bye." And I hung up. Seems very fishing to me.
