Since you have the Email used to open the account. i think it is very easy to recover your account. why not go for Password Reset using the Email address in your account.
It's not that easy to recover a hacked account. They generally change the email and password, that way the original owner can't do anything but follow the previously mentioned procedure.
After then, you can add more security in your account like Email notification when you log into your account.
This option does not exist, you just have to be careful with the security of your account.
