Has anyone ever offer a CA a $50 "PFD" to remove a collection that has already been paid (2-3 years ago). Fake them out, and say that a $50 collection is still showing on your credit report and you are willing to pay $50 to have the tade line deleted.
I would just dispute it. First, with the CA, then when you get that card back, go ahead and dispute with the CRA.
How do you dispute a debt with a CA whom you have already paid thereby admitting that the debt was yours and the amount was correct? Same for the CRA.
