Maybe you need to talk to support people.
If you are playing game on one device, and then someone starts up game on a different device (into same account), then device you are in will pop up logging you out because the other device game was started.
You can restart your device and it will logout whatever other device it was that had also started the game.
If you are saying you were playing on your iPad (for example), did a friend or family use your phone at same time and startup the game there too ?

Yes, you can try and open a Support Ticket with Kabam, asking to change your e-mail or password for the game. You will need to answer the long list of questions to prove the account is actually yours (original summoner name in game, first 2 real money purchases, when did you first download game, etc)
But if the OTHER device (or maybe was it an old phone you gave away ?) was the first device you ever used, it might still be able to play as you even without having to actually login with email/password. That device may have that account is the “default” account. (??)
