Cash Advance USA Said I had a lawsuit of a pay day loan web, Internet

I recieved a phone call TODAY 07/31/2012 from a Mr Jones. He started the conversation by saying I was being takin to court from Cash Advance USA for getting a $300.00 loan that I have not paid on. He told me I had a right to an attorney and if it went to court Id pay over 8,000 in fines and fees. He told me that I could not speak with the people handleing the cash loan because they have legal restraints against me. I then told him before I say anything further I was going to check my bank account for this transaction because If I owe it Ill pay it but Im 100% sure this transaction never took place. He then told me I had 30 minutes to return a call to him.I called my bank and the particular Month he said this transaction took place my account had not even been opened. I have yet to return his call but Iam to give him the information. It just doesnt add up. The scarey thing is he had all my bank account information, IP address, Referances that I have used in the past, Social Security Number. Dont know how but he did.He also said prior to our conversation had I been contacted about this issue and i told him NO ! He said well dont interupt me and let me exsplain that is when he began to tell me all this.
