Eurojuris Editing job - non-payment, potential scam Ukraine Internet

I applied for an editing job with Eurojuris. They would send me contracts to edit for correct grammar and punctuation. I did 5 jobs equaling 7 documents for them. I was supposed to have been paid on 4/21/15, and have received nothing. No communication from them, no requests to cash checks and keep my portion. I did provide routing number and account number for them to deposit into.

I am owed about $500, and after reading other reports, am afraid I've been duped. I did investigate them before agreeing, to check legitimacy. These people are good.
