Did you submit your ticket thru Comodo Support? http://support.comodo.com/
If so, log back in, and click on "View Tickets." The third column will show Status. By clicking on the ticket title, you will open that ticket, can read any replies, and also reply there as well.
Oftentimes, Comodo's email will be caught by spamfilters and redirected; if you use online email, you might check your junkmail/spam box.
PS: Realizing you probably went thru Trustfax support instead of the main Comodo Support page, the process should nonetheless be the same.
