what does the contract that i hope you got signed say?

if you didn't get a contract signed, you kind of brought this on yourself. if you did and he's violating the terms, take him to small claims court.

if there isn't a contract, consider walking away and finding someone else to do it.

i'd highly suggest avoiding rentacoder and simlar sites. they do not typically produce high quality work, and there is often a language barrier issue.
