eFootball Mobile Failed to Find My Account Despite Google Link

I am writing about a serious problem with my eFootball mobile account, which is linked to my Google account and registered in Kenya. Since 28 October, I have been unable to log in to my account. When I try to sign in, the game shows a message that no data is found for my email, as if my account does not exist anymore. I have spent around 1,000 KES and a lot of time progressing in this account, and I am very worried that all my game data and purchases have been lost. I did not delete my data or violate any rules to my knowledge, so I do not understand why my account cannot be found. I kindly request that you investigate my Google-linked eFootball account, recover my game data and restore full access to my account as soon as possible. If recovery is not possible, I would like a clear explanation of what happened and information about compensation for the money I have spent.
