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.
