I have received many calls from this number.  A couple of seconds after answering, a recorded woman's voice says "goodbye" and the call is disconnected!

I received several calls from this number over the past few days, most times a recorded voice says "goodbye" and the call is ended, one time a man yelled "is this and he said my name" and then he hung up!

They called and told me I won a vacation because of my recent travels.  I havent traveled in over a year. Told them I was at work and didn't have time and ended the call.

Got a call from this number today - didn't pick up as I didn't recognize the number.  No message left.

I am registered with the national do not call list, what good is being registered if you still these calls, and why with the technology we have we can not permanently block these calls from our own phones??????
