Something similar happened to me a year or two ago. I sent money down with someone to pay a friend in the yard who had cleaned the house. When I got down I assumed it was all taken care of.
The friend didn't say anything and I thought everything was good. Until one afternoon she came over and had had a likkle too much rum. LOL! She was going on and on about something and I didn't understand what the hell she was talking about. A couple days later I asked her to clean again and went to pay her and finally said what about the rest? Rest? Didn't you get the 'other' money I sent you. She said yes, but not all of it. LAWD......
We got it sorted out, but the lessen here was, always ask the person. Don't assume.
I have also had to say to people, sorry but I sent it and it no longer has to do with me. You need to go to the person and discuss it... Sucks cause as most of you know, alot of Jamaicans in Ja with not deal straight up with one another.
