eFootball Android Account Email Change Request

I am an active eFootball player on Android and I have lost access to the email address linked to my game account about a month ago. Because I cannot enter or use this old email, I am worried about the security of my account and I am unable to manage my account information properly. Up to now I have not been able to contact support through the game or Konami’s channels, and I am therefore writing this complaint to request help. My clear request is that you assist me in changing the email address registered to my eFootball account on Android and link it to a new email address, after any identity or account ownership verification you require. I kindly ask you to review my situation, guide me on the necessary steps, and complete the process of updating the email address on my account as soon as possible so that I can continue using the game safely.
