RJM Acquisitions LLC Collecting on a Citizens Bank account I never had Syosset New York

I received mail in my post office box from RJM Acquisitions LLC on 3/7/2009. The letter claims that RJM purchased from Citizens Bank an overdrawn checking account that is supposed to be mine.

This is some info they provided about this account:
Account #: 6204950596
Amount overdrawn: $118.49
My SSN#: 200XXXXXX
My previous address: 7302 Sherwood Road, Philadelphia, PA 19151-2229

They're telling me that if I decide to settle in one lump sum I'll only have to pay $59.24. Or, they'll accept $71.09 in monthly payments of $23.69. Or, the whole 118.49 in monthly payments of $11.84. And they're saying I have until 4/16/2009 to respond.

However, I've never had an account with Citizens Bank. My SSN doesn't begin 200, or even with a 2. Neither I, nor anyone in my immediate family has ever lived at that address.

So far, I've just sent a query to Citizens Bank, and filing this report with you. I haven't tried contacting RJM because I'm not sure if they're a legitimate company or if this is a scam, or an honest mistake or anything.
