Complaint Review: Credit and Collection Solutinos Incorporated

I received a bill a while ago and never paid it because I did not know what exactly it was referring to.  I decided today to check it out and found another person claiming the same thing I am.  The number on the letter is invalid and there is no other form of communication besides the address where I am supposed to send my check or money order for a substantial amount of money.  

This is obviously a scam.  I never received any calls or anything like that so I just figured this out on my own.
