Criminal Justice Legal Law Services I keep getting phone calls threatening suit for a payday loan I never applied for, got or used. Manhattan NY

I keep getting phone calls and emails from this group telling me that they have a complaint that they are going to send to local authorities against me.  What little information I have been able to gather, they alledgely deposited money into my bank account at a time when I didn't have one.  In the emails, they state that they have all kinds of information about me - however when I reply to the email and ask for specifics, I don't hear back from them.  I was the victim of identity theft not once, but twice and on the advice of my attorney, I ask them to give all pertinent info so that I can add this to my case, but I don't hear anything back.  I've noticed other people seem to be having some of the same trouble, even though it's not to the extent that I have.
