My question involves collection proceedings in the State of: Tennessee

I received a subpoena to produce documents in a bankruptcy case. My name and address on subpoena is exactly right. I have never heard of the debtor or any of his affiliates. I have no document or information. They must have mistaken me for another person somehow. We actually researched the debtor and found a person with my name he is affiliated with.

I have attempted to contact the law firm numerous times and I have left numerous messages. They always say they are out of the office and they never return my calls. Do I need a lawyer ? If so what type? If I do make contact with the firm what documents do I need to be released from the subpoena
