Slow turnaround times and impossible requirements

Experian requires documents other bureaus don't require to rectify information on a credit report and they take forever to respond to queries and complaints. those 20 days they talk about are a myth- it takes over a week just to acknowledge receiving a query. I submitted my query on the 29 Aug 2025. It was logged n the 18 Sept 2025. I provided a court order, why cant they call the court to verify the information provided? This incorrect information on my profile is making life very difficult
