Who called from 3306190883

Caller called me by name when I answered and then kept saying my name repeatedly such as;  hello...hello...hello...

Caller asked for my husband by name, when I asked who's calling, they hung up. We're in NJ and were robbed last year so I'm very worried about the  possibility of someone just checking to see if we're home.

We keep getting calls asking for people in the family and when we ask what this is about they hang up.  How can we stop this?

Same old crap. Keep getting calls from this number. I never answer them. Added to my phone contact list as "DON'T ANSWER". From here on out I'll know not to answer.
