My health insurance company issues me 4 checks totaling 20000 dollars in dec 2009. Someone stole is and deposited it in their citibank joint account which was under a person with my name and another persons name. This happened in march 2010. The other person signed the backs of the check. My insurance company checks were issued from their jpmorgan account. My insurance company is not being helpful in getting back the checks. I signed a affidavit with my insurance company saying someone stole the checks. This is why they got me the info but they aren't going after the money. What are my options for getting back the money. I am in new York and these people who stole my checks are in California.
