Lost Account

I lost access to my FC Mobile account after trying to log in with the email address linked to it. My old tablet could not support the new version of the game, so I installed FC Mobile on my new tablet. However, when I tried to sign in, I received an error, and somehow a new account was linked to my e-mail replacing the old one. Unfortunately, I don’t have my Player ID (UID), but my account is still visible in my second account.  In my second account which I play on my phone I can see my tablet profile in-game friends list. I have screenshots from my phone account showing my tablet team profile (I can provide them if needed). I have also the receipts of my purchases which I made from GooglePlay.

I can provide all the information of my phone account. I can provide all the information of my tablet account except the UID.

Thanks for any help.
