Can’t log in – amazer - KPOP FAN APP Review

I hope this problem gets fixed. I already have an account and I can’t seem to log in. Without logging in I also can’t send a help email so I have no choice but to write a review on it instead. Whenever I tried logging from Facebook, google, or email. It tells me that the username and email has already been registered? Yet I haven’t been logged in at all and it keeps telling me to log in when obviously it won’t let me. I’ve tried deleting the app and reinstalling it multiple times and still can’t log into my acct. I hope this gets solved. Other than that it would've received a better rating.
