I lent $8k to a jewish rabbi in S.F. back in April of 2011 to help fund "Passover" celebration. I was promised payback within 2 months- which was stated by the Rabbi in an email that I still have. He has done nothing but come up with excuses as to why he hasn't been able to pay back the money and eventually stopped answering my calls and responding to emails. It has now been 2 years since I lent him the money and I'd like to know the best method or approach to take in getting my money back?
