KONAMI Support Has Not Helped Recover My Hacked eFootball Account

I have been playing the eFootball mobile game for about one year, and I am writing because my account was hacked around two weeks ago. Since the hacking incident, I have completely lost access to my account. At the moment, I only have a photo of my squad as proof that the account belongs to me, and I do not know any other account identifiers that I can use.

I could not contact KONAMI support directly because I do not know the correct place or channel to submit a complaint, so I am using this platform to explain my situation. I kindly request that my eFootball mobile account be recovered and returned to me, or that you provide clear guidance about what information or steps are required so my account can be restored as soon as possible.

I expect your support team to investigate the situation, help me verify ownership of the account using the available squad photo and any other possible security checks, and ensure that I can safely access my account again.
