Called on my cell. I did not answer. No message

All the calls from 347-535-5217 have been anonymous
so far. My phone display did not show the name of
a company, or a organization or individual owning
this number.  Who is hiding behind this number?

WE REFUSE TO ANSWER ANONYMOUS CALLS!!!

"This is Josh from Customer Service.  Can you hear me okay?  (Yes.)  You've just won a trip to the Bahamas.  (Click.)"  Of course it's a scam.
