scam alert headers

so far i been scammed, does anybody know a john darling from clarklake ,mi? he has a set of headers on craigslist advertised as 1 3/4 small block headers, so i jumped on the deal, i paid him via green dot card-like a pre paid credit card. i was worried that they wernt 1 3/4, i called him and asked him to verify the part# on the header flange, they are 1 5/8 ,so i asked him not to send them ,that i already have headers that size, he was pleasant and understanding, he said he was going out of town and would send it back thru pay pal, as of yet i havent seen a dime. we are only talking about a 100.00 bucks. he used the prepaid card on the 23rd of august, today is the first. i could really use the 100.00 back, he also has a nice looking set of big-block hugger headers on craigslist also.i have his bussiness phone # if everyone wants to take a turn a phone harrass him!:violent1:
