Hey 64b6l7x0l9vm,
Sorry to hear someone else may have 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 assist with here on the forums.
Once you've gone through the steps linked above, you can use the Contact us option at the bottom of that page or this link to get in touch with the support team so they can help with the account recovery. They'll be able to work with you to clear this up from that point, thanks!
