Someone from this phone number keeps calling then hanging up.

Persistent guy who would say anything specific.  Sounds like a bad sales call or scam of some sort.

The guy that sounded like a robot call specifically mentioned my full name  saying that if it is not the person to hang up because there are some sensitive information he will disclose. I listened to the message and the caller wanted to return  their call with 888 number. Did not say what company he is from.
