Received a call from this number tonight

I have received calls from this number two days in a row.  I screen my calls and try not to answer numbers that I do not know.  Both times the caller did not leave a message.  When I did a reverse number look-up on White Pages, it came back as an invalid phone number.  Sure it must be some sort of scam, but I'm not calling it back in case it's one of those scams that somehow charges you an astronomical amount of money for a toll call if you answer or call back the number.

I received a call twice today but didn't answer either time

I just got a call from this number at the moment.

The caller told me that she has "all of my information," and that I have won a fantastic prize award, including a complete home makeover and round-trip tickets to Las Vegas.  I asked her if I can call her back at her number and repeated the number to her.  Silence on the phone.  I asked the same question again, silence on the phone, and then she finally said "ok."  I ended the call.  This appears to me to be a scam.

Got a call from this number, all that it said was goodbye.

Received a call from this number, I answered and it was to tell me that I qualified for a $25,000 home makeover, jokes on them I never entered anything like that because I rent an apartment!
