I've been hacked

Q u o t e:
I would like to know if the hacker has access to my personal information, like my SIN number, my bank account (I do some online banking)? How should I go about to protect this?

It's difficult to say, Celwin. They would not be able to obtain this information through us, but if you had malicious software installed on your computer and have typed out this information, it's possible that they have acquired this information as well. While I do not have any specific information to provide on how you should go about protecting your other accounts, I encourage you to review the following support article we've created to help our players better understand what it takes to keep a computer secure:

You've done the right thing by sending an e-mail to our Billing department to ask that the Authenticator be removed from your account. As an alternative, you can call our Billing department during normal business hours which may a bit quicker. They can be reached using one of the following numbers:
