My LF ad = a rip off after pymt 4 my UFC Hoodie

Looking 2 buy this UFC hoodie I was diligent keeping the ad up 2 date. A Kijiji user msg'd me about 3 wks ago he'd given 1 to his gf and wasnt sure if she took it when she left but new it was identical. So he'd gbtm asap. Just over a week ago I sent him a msg he replied he had it and He was happy 2 sell it 2 me. I DID A HAPPY DANCE OMG my persistance paid off. I got it finally. After many msgs, texts, emails talks we'd established a level of trust, I sent his $ via e-transfer..I never saw my hoodie nor did he answer another msg. I have his link, c/p's + pics of all info. I don't have authority support. I was told although we both live in Ont I'm in S. Ont. He's in N. Ont. Basically 2 suck it up. I paid $50 for a headache. What he did isn't right I don't want this 2 happen 2 anyone else so "Buyer Beware" and msg me if you want details/proof.
