I received a phone call at my work number with an ominous sounding message containing XXXX legal language. Since I ca n't take personal calls at work, I waited until I got home to call the number back. I found out that this company also contacted XXXX my relatives. 

When i called the number back, XXXX verified the last XXXX digits of my SSN, had my address, but had an incorrect e-mail address. He gave me some spiel about XXXX loans that I owed, but could not provide me concrete information on who originally made the loan to me, when the loan was made, and basically any information to verify what the debt was. I have no idea what his call was about. Further, I asked if his company was licensed to collect debts and he said he did n't know. I asked for the address and he was originally evavise but provided me a XXXX. XXXX. I instructed him not to call my work or my relatives, and when I attempted to provide him the best number to contact me he said he did n't want it. He 's trying to scare me into paying something that he has no idea what it is and ca n't prove that I am legally obligated to pay. I want his company to never contact me, my work, or my relatives again.
