Didn't leave a message. Probably advertising or something. Agree with the people above.

This number called I didn't answer but called back. A female answered asking how May she help me. I asked who she was and she hung up in my face. Second call they just hang up. Third call it was a female again who said hello. I told her never to call again. Obvious scam
