Bad poor bad poor service

I received an email confirmation from Nimble Collections for experian to remove a disputed account on their listing and today comes with another story of credible evidence to retain the account in their listing. It does not make sense to be instructed by the Nimble Collections and have credible evidence to have it on listing. Maybe I don't know what a credit bureaus is doing. Clearly this does not make any sense some poor service and misunderstanding. Supplier instructs removal but experian have their own credible evidence that the account remain on the listing.
