I singed up with 3 accounts of my I charged already for two of them for 180days each account.
after I charged I received OTP ID & Auth Code, I sign up on my iPhone OTP ID & Auth Code and there no option to logout which mean I have two differents OTP ID and two differents Auth Code, on same phone. the problem is I can't log out from the first one.
the third account it's my brother's account I put my number instead his phone number, it's was my mistake.
for change number I should be register which mean I in trouble.
I tried to delete OTP and downloand it again but it's still on in the first account.
