This company is called ERS, they are a collections company.  They do not adhere to the collection statutes of the states they call, nor are they reputable in my opinion from my dealings with them.  They claim to have an account that is delinquent they wish to discuss but will not state the original creditor, balance due, or send anything in the mail.  Instead, they want your social security number, address, date of birth, and place of employment before discussing anything.
