The sponsor/billing doesn't pay me money. At first they forgot payee name on check by my request. Then they sent my checks to wrong (cutted) name, saying me everything ok. At last when I'd sent to them the check scan with wrong printed name, they replied one time and died in silence. It was month ago. Now all my emails are without replies. The person who communicated with me is Richard Mazur.
Now they owe me more than $1k and have no willing to solve the problem and pay me.
