Request For Help In Recovering My Gmail And Google Play Accounts

For about a week now I have lost access to my Gmail account and, as a result, also to my Google Play account and my eFootball game account linked to it. When I try to sign in, I see a “Couldn’t sign you in” error for the address kinj*****@gmail.com, which makes me think my account has been hacked. Since realizing I could not log in, I have tried all the recovery methods offered by Google, including the account recovery page and other suggested steps, but none of them have worked and I still cannot regain access. Because this Gmail is connected to my Google Play profile, I have also effectively lost access to my eFootball account and the purchases and progress linked to it. I kindly request that my Gmail account at kinj*****@gmail.com be restored to me and that access to my Google Play account and my eFootball game data and purchases associated with this Gmail be recovered as well, or that an equivalent solution be provided so I do not lose my data and purchases permanently.
