Hi, welcome, and congrats on earning your CISSP!
You should have received an email within 2 weeks of receiving your formal CISSP congratulations email inviting you to claim your badge. So maybe check your inbox / junk mail again.
Once you have that email you can go through the process to link the badge to your Acclaim account.
If you definitely don't have that email yet, you've done the right thing in emailing email@example.com.
Another likely faster option rather than waiting for a response to your emails is to call Member Services using the details found in the contact section at the bottom of this Community site or the main ISC2 site.
