This is what i did.. I had a friend of mine i gave him 3grand..He said he will give me in 2 to 3 months and i was ok.But it passed 6 months then i asked him again he said nxt month then i thought he will give me when he has it it crossed 1 damn year and he doesnt even talk about that as if nothing is between us. Later i asked him again he was kind pissed coz i asked him my money..I was like WTF. Then i called his parents in nepal then told them what happend and told thier parents that my one of the family members will be coming to your house to pick it up. They were kinds emberassed and i had no options it was not a matter of 3 hundred..But their parents were nice to me they apologised to me and i sad they dont have to your son has to.After 2 days he comes to my door gives me exactly 3 grand 100 dollor bill and tells me you shouldnt have called my parents coz it was between us...I was like do i look like i care ??? 
So if its big amount i suggest you call parents and tell them what happened.
