auto scam

I was scammed trying to buy a 2007 Dodge Ram 1500. This lady, allisan1969, was selling truck for 1/3 of it's value, sounded great. $5200, great price. Sounded to good to pass up. Was supposed to be sending money to ebay representative, to hold onto until i got the truck,i was to have 5 days to try it out,sign papers and accept deal. Sent money Western Union to supposed representative, and never herd a word after that. I am o embarassed to tell anyone, that i screwedup. the reason for selling so cheaply was that her husband had been killed in Iraq three months ago and she was selling her house also.
