DOFD - Date of first delinquency........the delinquency that lead to the charge off/collection status, this is what CRTP goes by.
Check your state law specifics, but if DOLA is 4 years or more ago and you haven't reset/tolled SOL, and your SOL is 3 years, then it appears the accounts are past SOL.
For the paid traffic, I would send GW letter.
For the CC, you say it is disputed........did you dispute with the CRA, the OC, the CA?
