Number on my caller ID, I never answered. Id  "Celebration"

I receive several calls to my cell phone which I do not answer
as I do not recognize the number.  This happens sometimes
up to 4 or 5 times a day.

I recently changed my cell phone number and only people that
have it is my immediate family and a few very close friends.

None of the companies that I do business with have my new number.

Thia number calls at least twice a day, usually in rapid fashion.

I got a call from 712-429-0248.  Told me that I was 1 of 4 phone numbers in the state to win $1,000 shopping spree.  He said he's from Value Benefits of America.  He also used the 712-429-0250 number.

He gave me this #8669168814 to call.  His name was "fred slaytan" and he said his id # is 5155

They called twice this morning.  Once I didn't answer, second time it was disconnected when I picked it up.  No message on voicemail.  Caller ID said "IOWA".
