NOt only is their reporting of a good-will request as a dispute improper, their subsequent reporting of a resolved dispute is even more improper.
If they treat a letter as a dispute rather than as a good-willl request, they have acknowledged that they consider it to be a direct dispute under the provisions of FCRA 623(a)(8). They are then oblligated to send the consumer a formal notice of results of investigation of the dispute within 30 days, which either verifies the accuracy as reported, corrects the reporting, or deletes it.
They cannot both treat a letter as a direct dispute and then fail to conclude the dispute by a formal notice of results within 30 days.
They are in admitted violation of the direct dispute process if they simply report a concluded dispute without sending the required results of their investigation.
I would contact them and request deletion of any reference to any dispute.
If they fail to comply, then send a formal complaint to the CFPB for either their mistreatment of your letter, or for their violation of the requirments under the direct dispute process.
Time for a formal complaint to the CFPB, asserting either misreporting of a dispute when there was none, or alternately, misreporting of their formal conclusion of a direct dispute when they have not sent any notice of results of verification of any direct dispute to you.
They cannot hold that you have disputed, and then not respond with results of their investigation of the "dispute" within the requried period, and then additionally mis-report to the CRA that they have concluded a direct dispute.
They are compounding their screw-ups with each treatment of your prior request.
