False Claims of Litigation

After receiving 3 calls from an "attorney" saying I had pending litigation in their office and I or my attorney had to contact them today or they would tell the courts their case was without contest.  I called their number 203-484-3516 and spoke with Leslie.  They could only tell me that the case was against my wife for an old debt.  (She was being hasassed by a payday loan company years ago, that she/ we had no knowledge of.  So I am just tresating this a a scam as no written evidence was offered to give to my attorney.
