This is so simple to solve. Have one of your family members send Western Union. Then grab a motorcycle taxi and tell him u need to go to a Western Union. (Google the address and call to make sure). Then when the motorcycle taxi drops u off he is to wait for you while u pick up the money. Then he takes u back and u pay him. Simple.
I don’t buy the notion that Western Union offices r all “confused”. Most speak English. And with Google u can search WU nearby thru the WU app. Then find one and call. Simple
