Who called from 2012049805

Calls my private work number.  Message says it's a collection call but never says who they're calling.  Just leaves a number to call back and a reference number.  I just delete the message.

This same number keeps calling my house and I KNOW we don't owe any money and when you call back the 866 number they give you nobody answers.

Phone number keeps calling me and never leaves a message.

"Weehawken NJ" shows up on the landlady's caller ID -- but there's no Weehawken telephone exchange.

Called my work #.  Asking for me by my full name - i never use my middle initial.  Then asked ME to verify my address and social for them.  Yeah right!
