Any dispute is limited only to the specific item of reported information that is asserted to be inaccurate.
The statement that you "disputed" does not identify what item of information was the subject of your dispute, so it is not possible to comment on whethr the verification of its accuracy by the CRA was proper.
As discussed in prior posts, the collection should apparently be excluded based on expiration of more than 7 years plus 180 days from the DOFD on the OC account.
The debt collector was required to have obtained the DOFD and reported it to the CRA no later than 90 days after they reported their collection, and thus it MUST be of record in your credit file FCRA 623(a)(5). You can obtain the reported DOFD either from a complete credit report, such as via annualcreditreport.com, or directly from the CRA.
If the reported DOFD is more than 7 years plus 180 days ago, then the fault in lack of exclusion rests solely with the CRA, and not with the debt collector.
However, if the reported DOFD is less than 7 years plus 180 days ago, permitting it to still be included in your credit report, then the fault resides with the debt collector for their repporting of an inaccurate DOFD. You should, in that case, file a dispute of the accuracy of the reported DOFD, providing whatever information you have to show that the DOFD was prior to the reported date.
