Who called from 7027891548

they keep calling and do not say anything they are harassing me.

Same deal, I've had seven calls from this number over two weeks, no sound from the other end.

They just called me, no response but while on the call another call was connected in.  The after the third party joined in the guy who called me said, oh sorry and hung up.

Same is happening to me and they don't give up.

same here. going to block the number.
