The device that listed me as ios13.4 is fraudulent activity on my account my iPhone is and remains a 6s plus operating on ios9.3.5 and I want my information changed immediately and I am also not anonymous as that was fraudulently transposed as well

I can't remove it because it is a screen overlay and I want it changed back to mghamilton31@icloud.com and the user name Matthew grant hamilton like I originally created the account to be please do not allow anymore changes I also only ever use the browser because I've been unable to download the app because of hacking
