Section 809 of the FDCPA http://www.ftc.gov/bcp/edu/pubs/consumer/credit/cre27.pdf requires 3rd-party debt collectors to give debtors written notice of debt (the key word is *shall*) :
"§ 809. Validation of debts
(a) Within five days after the initial communication with a consumer in connection with the collection of any debt, a debt collector shall, unless the following information is contained in the initial communication or the consumer has paid the debt, send the consumer a written notice containing—
(1) the amount of the debt;
(2) the name of the creditor to whom the debt is owed;
(3) a statement that unless the consumer, within thirty days after receipt of the notice, disputes the validity of the debt, or any portion thereof, the debt will be assumed to be valid by the debt collector;
(4) a statement that if the consumer notifies the debt collector in writing within the thirty-day period that the debt, or any portion thereof, is disputed, the debt collector will obtain verification of the debt or a copy of a judgment against the consumer and a copy of such verification or judgment will be mailed to the consumer by the debt collector; and
(5) a statement that, upon the consumer’s written request within the thirty-day period, the debt collector will provide the consumer with the name and address of the original creditor, if different from the current creditor."
I have been threatened by this company for a bill they say I owe from 2 years ago and they have not sent me any paper work on what they are saying that I owe. They are constantly calling me at work threatening to send a debt collecter (someone who serves leagal notice to my job). I am at my whits end with this company. They have not provided me with any paper work about what I owe.
