Keep getting calls from this number, but there isn't anyone at the other end

Got 5 calls from a woman calling herself Elizabeth with an Asian Accent (Chinese) Said she was calling from"Beyond Smile", told her to leave me alone...She rang back 5 times abusing me...Had to take phone off the hook....gets scary that these people know our names and where we live...no privacy anymore.

I just got a call from this number claiming he was selling coupons and then said that I called him and gave me my husbands name and said it was his name.
