Hey ccb2015,
Sorry to hear someone else had gotten into your account. If you haven't already, please be sure to go through as many of these security steps as possible to help get your account and system back into your control.
After that you'll need to get in touch with our support team to help recover the account itself. As they'll need to discuss private account details, that is not something we can look into or change here on the forums.
Once you've gone through the steps linked above, you can create a new case here to get in touch with the support team so they can help with the account recovery.
