Criminal Records, Expungement court order for production of records

[jacemace]

I got a letter in the mail today from my bank telling me that there is a business that I have used my card at is under investigation and has subpoena'd all records associated with each account number. The business is a massage parlor that I went to over a year ago. No prostution took place but it was solicited to me. Should I worry about this? In the copy of the subpoena it does not mention what the records are being used for, there is just a 2 page list of account numbers. What do I do from here? Is this about me or the business?
