Complaint Review: Brittany Garver

I have got a few emails from a lady goes by the name Brittany Garver claims she is a Attorney for cash advance inc.. Stated in each email I got that I owe a payday loan and to sign these loan documents I sent you today, so we can settle this matter as quick as possible, She also stated in this email that if I don't agree to sign them or email them back soon, she would put a lawsuit against me. I have no idea til this day who she really is or what she is talking about. I did not sign any loan documents she sent to me or will I ever do such a crazy thing like that. I just want to find out who Brittany Garver really is and why she is sending me these emails. I do plan to keep all the emails of her treaths to me. Please help me get this resolved soon. Thanks
