Can anyone help me to recover it? Hacker is trying to stole my BCT account.
If you have a phone number or recovery email attached to that account it would be easy to recover.
Sometimes we tend to forget the password and we might think that it's hacked, if you connect your phone number to your gmail account, it's impossible it can be hack, since it will be access in different location, google will ask confirmation for your account.
That's my experience and I just want to share based on my experience.
The gmail email address itself can easily be recovered since it think you set up security questions and alternate email addresses to recover it in case it gets lost. Now it gets a little trickier if the hacker manages to access your bct account since there's a strict policy i think when it comes to changing email addresses, mainly for security of it's users. It would be better ans easier if you could recover your email address first.
