Request for Account Recovery FC Mobile AccountOverwritten by Guest Account

I accidentally overwrote my main account with a guest account when switching accounts in FC Mobile. I need help to recover my main account.

My game UID is 981555241369300996.

Even when I log in with my EA account, it still only loads the guest account. Logging in with my linked Google email also only opens the guest account.

Could you please help me restore my main account? Thank you!
