at least 1 CRA scans this documentation into their system and dumps the paper-
They DO NOT send this "proof" along with the dispute even though they are required to by FCRA - they take everything you send and convert it to a 2 digit code that is sent to the creditor or cross referenced on Oscar -
You have to assume they have nothing when subsequent disputes are placed.
Yes- they know if you have disputed the item before-
In your dispute- clearly state- "here is the requested additional information you requested to re-investigate this item per FCRA."
or they will say it was previously investigated or frivolous,
