ACS legal for CashAmerica Harassment, Legal Threats, Claiming Fraud Internet

I received a phone call this morning from an individual named Eric Johnson, I believe, with a very strong Indian accent. He left me a message saying he was calling in regards to a legal matter, from the FDIC, about me committing fraud with my husband's information. I called them and they refused to talk to me about it, even though they called ME. My husband called them and they told him that I took out an online cash advance loan sometime between March 2009 and December 2009 and never paid it back. Then they said that they were suing us for the balance and that we needed to pay off the debt or go to court. They provided our bank information and personal information including our old address (we moved August 2009) and said the money had been deposited directly into our account. I have pulled all of our statements and spoken with our bank and there is no record of this deposit.
