Only mentioned my name and a file numbe and stated they needed to solve this problem. Didn't state who they were, why there was a problem or any other information.
Said I owe them money and they sent me 4 letters to my parents house which I haven't lived in for 2 years.
Mentioned my first name, said this was a followup on my files with them. Despite the fact that I instructed them, by mail, not to call me. Once you let them know in writing not to contact you, calling you is a violation of the Fair Debt Collections Practices Act.
They are a total scam. Do not give them your money
