can anyone tell me what i can do, i sold my almost new savage to _____ in canada and it was part trade cash deal, i got the trade part but not the money he said he sent it but i have never got it, and he said he mailed it on the same day as he mailed trade, my question is what can i do to get my 180 bucks, he has the savage now and i dont have my money

i learned never to ship till payment received and never deal with canada
