eFootball Account Lost After Reinstall – KONAMI ID Shows No Data to Transfer

I have been playing eFootball on Android and my game data was registered with a Konami ID. Today at around 2 p.m. I accidentally uninstalled the app, and after reinstalling it I have lost access to my account. When I try to transfer my data using my Konami ID, I receive an error saying that there is no data to transfer, and the game then leads me into creating or using a completely new account instead of loading my existing one. Because of this, all of my previous progress and data appear to be lost. I request that my old eFootball account, which was linked to my Konami ID, be fully restored and that all my progress and in‑game items be recovered. I would appreciate your urgent help in resolving this issue and restoring my original account.
