1-876-788-9788 JM Pots phone gave address 327 Tall Oaks dr. SE Conyers, Ga 30013. saying they are part of publisher clearing house and we have won a big amount of 2.8 million. the caller kept calling repeatedly. I finally answered and said it was a scam. He called me a stupid [***] and said he was going to kill everyone in my family and why I did that and he was going to send his men to take care of me and my family. Wow! he also said was was just as crazy as the person who killed all those people in Las Vegas. Why is all our information so public to people who want to steal and hurt people who work hard?
