Who called from 6478473427

I'm getting calls from this number

I called them back and they said they where calling from a sweepstakes redemption centre?  I told them to remove my number, no further conversation necessary.

I called the national do not call list & filed a complaint against them as my number is registered.

They called and asked for my wife by name. I asked where they were calling from and they said "The Redemption Centre". I said "Redemption Centre" of what and she asked if this was Mr. K. I asked "Redemption Centre" or what and we danced back and forth for 5 minutes till she told me "Redemption Centre of Dream of a Lifetime" and then hung up.

Asked for me by first name & that alerted me to hang up right away.
