Who called from 4237903165

They keep calling, when I call back their number is dis-connected. Sound like a scam?

These calls are a nuisance and an invasion of privacy.  Does anyone know how to enforce  the DO NOT CALL LIST?

Someone with a very heavy accent just called me from this number.  When I told him I wasn't the person he asked for he asked who I was I told him my name,  said I don't know the person you are calling for and I'm waiting on a call.  He said okay I love you.  I just hung up.  Very strange.
