Voicemail tells me that someone filed a complaint against me on a debt. Said myself or my lawyer needs to call back by the end of the day. Said they had called and sent several letters which I never got. I'm not calling back. Way too many complaints against the company as being fraudulent. If you google Account Discovery Systems, you'll see the other phone numbers they have and all the complaints against them. Do not bother with them. I blocked the number.
