ALL MY MONEY STOLE!

I am a young man living in wisconsin with very little money and a 2 month old baby girl. I am in desperate need of a motor vehicle and I saw one online and I purchased it. I thought that it was safe because ebay was the third party. Well at least I thought! I paid for the car in full pulling out all money I had and asked the man I do not know how many times if it was a scam. He reasured me that it was legit and I felt safe with ebay suppose to be helping me! But I tell ebay I have not receieved my item and I get no response from them! Now I have no money, no car and soon no place to live with me and my daughter! I am the angriest I have ever been in my life! I cant believe that these cold heartless basterds can wake up and go to sleep every day knowing that they have put someone out on the streets! And it sucks because what can I do now. Absolutely nothing. some punk is running around blowing MY MONEY on whatever the hell he thinks is important! And it makes me angry that I have gotten no help from eBay at all in anyway!
