Stolen eFootball Mobile Account After Hacker Changed Linked Email

I am an eFootball mobile player on Android from Kenya and my game account was stolen today. The person who accessed my account changed the email address linked to it, so I can no longer log in or manage my profile. This account is important to me because I have made in‑game purchases on it and invested a lot of time and effort. I have already contacted eFootball/Konami support about this situation, but I have not received any response yet and my account is still out of my control. I kindly request that my stolen eFootball account be fully recovered and returned to me, with access restored to my original details and purchases. I am ready to provide any necessary information or verification so that you can confirm that I am the rightful owner of the account and secure it against further unauthorized access.
