Received a call from this number, indicating they were sending "agents" to my work to serve me paperwork as I was being sued. They wouldn't provide any documentation to me in relation to the debt. I called the collection agency that is on my credit report and they had never heard of this company -- Millenium Asset Management. I don't know that this is a scam, but they seem sketchy after my last few conversations with them. They don't have an accent so they don't sound foreign or anything like that. I just have no idea who they are or how they even found my information. They said they were a "pre litigation attorney".
