can a hacked email account be closed?

Answer 1

if not used after 4 month.

if you know id and password, it will be possible.

Answer 2

Yes it can be closed, as long as you are the account holder. You will have to log into that account and under options change the password or delete the account all together. If you have any questions most email providers list ways to contact them directly either by phone or email support.

Hope this has helped you.
