Hi, im writing this because i think i got scammed. I had placed an ad on nikonians seeing if anyone was looking to sell a Sigma 70-200mm lens. Sure enough someone got back to me and we worked out $450 shipped. There were around 50 emails back and forth and he left his number if i needed it. He sent me pictures and was quick to make jokes, so basicly i felt there was NOTHING fishy. Anyways i sent him the money VIA money order and we confirmed he got it. At this point i began to lose contact with him as he began to not respond to emails claiming he was getting them and i wasn't receiving some. So now its been well over a month since he got the money and i cant contact him. What do you guys think i need to do next? ANY help would be appreciated! Thanks guys!
