Account locked

I received an email saying that due to technical anomaly my account(not this) has been locked, i needed to reset my password, even if i did it i still couldn't login, email or password not valid, i changed it again but the result is still the same, if i try to login via mobile app and authenticator i got an error, i still got access to the email linked to the account so it hasn't been hacked, i tried to change password already 2 times, got the notification password changed but doesn't work
