It's possible your emails aren't being received. Have you gotten any auto-response emails? You can try submitting a ticket directly through our system here:
If you have gotten an auto-response, what is the ticket # that you were given? I should be able to look it up that way.
Also, keep in mind, our ticketing system works off of the "Last Reply" date to put things in order. This means if you send a new email, it will push your ticket back to the end of the line.
