eFootball Account Hacked and Locked Out With C_NAJM_0028 Error

I use a Samsung Galaxy A26 and on Monday someone seems to have connected to my eFootball (efoot) account without my permission. After this unauthorized access, I completely lost access to my account and I can no longer log in properly. I now receive an error message on the screen saying that a network error has occurred and that an invalid command has been detected with the code C_NAJM_0028. Because of this situation I cannot use my efoot account at all. I did not share my account information with anyone and I did not make any unusual changes to my device before this problem appeared. The only result for me is that I lost my account access after what looks like an unauthorized connection. I kindly request that my efoot account be recovered and that access be restored to me securely. I also ask that any suspicious activity linked to this unauthorized access be checked and removed if necessary so that I can safely continue to use my account.
