Who called from 9012031279

I did callback........its a rewards center from visiting a site online....scam?? NO CLUE

Rang once, when I answered they hung up.

Rang once. I never picked up. Says Memphis, TN. Blocked.

Just another call from a scammer, who through different phone numbers calls multiple times weekly, offering a free $100 Walmart gift card. Sometime back, I found the owner to several of the phone numbers used by his operation, he's out of south Florida, he, just like the entire Obama administration should all be hung.
