Complaint Regarding Unjustified Credit Score Drop – Experian Credit Report

I am writing to formally raise a complaint regarding the sudden and unexplained drop in my credit score as reflected in my Experian report. Despite consistently managing my accounts responsibly, my score dropped by 8 points recently, without any clear reason or changes on my part.

For context:

Last month, my score was 624 and increased slightly to 627 in the 20th of Octomber. Just today, it dropped to 619. I have made no new credit enquiries or any application. My account utilization is consistently below 10%, and all payments are up to date. Comparatively, my scores with TransUnion (706) and XDS (749) are significantly higher, with all of my accounts in good standing across all bureaus. Given that I have put considerable effort into maintaining an excellent credit profile, I find this drop in score frustrating and concerning, especially as I have not made any financial missteps or changes that would warrant such a drop.

I request an immediate review and detailed explanation of why my credit score dropped by 8 points despite maintaining responsible financial behavior. Furthermore, I would appreciate clarity on how your scoring system is app**** in my case and what factors could have contributed to this sudden drop.
