Saw it on missed caller list. They left no msg. Came in as Out of Area. When I called back it didn't ring. Tried again and sounded like bits of a recorded msg with the signal dropping out.
Got 4 calls from this same area code, 1st two were 704-901-8045, and the other two were 704-927-8704. None of the times they've called did they leave messages. In the last 4 days I've gotten repeated scam calls from the supposedly IRS , but the messages left were from a guy with a strong accent barely understandable, and I'm thinking these 704 calls might be associated with those, another reason I don't answer.
