To Guest posted July 6, 2009, the reason the collection agency doesn't tell you this is because some of they actually buy the debt from the original creditor for pennies on the dollars. Then try to get you to pay the whole debt so they can make a profit by claiming they are collection for the original creditor when, in fact, the original creditor sold the debt and are no longer interested in collecting from you.
Know your rights! If you can, make sure you get everything in writing and offer a settlement amount to get rid of the debt once and for all.
