Please Help Me Recover My eFootball Account

I have been playing KONAMI’s eFootball using the account linked to the information EKPEIKOT and the email address Itamichae***@gmail.com. Last year, my KONAMI/eFootball account appeared to have been taken over by someone else, and the email address connected to it was changed without my consent, so I completely lost access. Since then, I have not been able to log in or use my account in any way. I have invested a lot of time in this account and have spent approximately 7,000 on it, and I do not want to lose my progress and purchases. I have not noticed any suspicious activity before losing access, and I have not yet received any help, as I have not been able to resolve this situation on my own. I kindly request that my KONAMI/eFootball account be recovered and that I regain access using my email address Itamichae***@gmail.com. I ask that you restore my account, preserve my progress and in‑game purchases, and help me secure the account so that this does not happen again.
