No response and service

I've been struggling for almost 3 months to get my report updated correctly on Kudough it shows that it has been updated and everthing is correct but still after 3 months my clearscore is still incorrect. I've contacted experian and mailed numorous times but i dont receive any feedback from any one. This is ridiculous everthing is cleared and up to date but there is still showing an account that has been closed in August 2023.
