I have been battling with the 3 credit bureaus for about 3 months now. I am not really sure if what I have in mind is actually a duplicate entry. Is an original credit and the collection agency that cover the same account considered a duplicate entry. Or is a duplicate entry just the same entry entered twice. If I am incorrect about the original & collection agency entry, could you tell me if it is legal to have both creditor and collection agency on the credit report considering that the creditor sells the account to the collection agency. Is that not double jeopardy?
