Recovering My Konami Account

I play eFootball on my Android phone (Tecno KL4) and on 16 March 2026 my Konami account email was changed without my permission, so I lost access to my account. Before this happened, my game progress was already linked with my Google Play account, and I believe this link can verify that I am the rightful owner. I have not yet contacted Konami support from within the game or via other channels. My clear request is that my original eFootball account be recovered and restored to me using my Google Play link as proof of ownership, and that the unauthorized email change be reversed so I can safely use my account again. I kindly ask you to review my case, secure the account, and help me regain full access as soon as possible.
