Who called from 4102200873

Just another phone spam scammer:  after 3 calls with dead silence on the other end, blocked.
see ya, key ya, wouldn't wanna be ya!

"Rewards Center"
asks you for your phone number, as a prelude to the usual advance-fee con.
Really?   How'd they manage to call you without knowing your number...
...unless, maybe, they used and auto-dial robot and called EVERY SINGLE BLOODY NUMBER in your area code/exchange!
If that ain't a dead give away for a scam, what is?
