I got several calls on cell, then tried to call back, it was busy. Then the call came again, it was really delayed. Finally the lady said I had won a $100 gift card and a $10 Walmart card. She wanted to confirm my email and I told her it. Then she wanted my address. I told her I wasn't comfortable giving it out, she said thanks for my time & hung up, after telling me she was from waka network.com. Now she just called my home phone. Scam??
