Refugee case

My sister lives in Syria and has a refugee application to US in process through UNHC in Syria. I meet with madam Codina at Codina International Group - Toronto office ( cic ) and she promise to bring them within six months, I paid $2500 and have signed contract with her on April 2013 and till now nothing happened. It’s been almost 6 months; I cannot reach her or her employee (case manager). Can you help me with a name of lawyer to take the case to the court?
Appreciate if somebody contacts me on [email protected].
Thanks
