So this is what happened.
I have 3 mobiles technically 2 are parents ones but nonetheless I play on them too.
There was ab existing account on one that I didn't want.
I log into the good account using my Google play as I don't know its username/password.
On the 3rd phone I accidentally bind my play account into the bad account and now whenever u turn on other phones it logs into the bad one
What do I do
