CO Customer Care took about 10 days to respond to one of my e-mails submitted last month. When I sent the e-mail, I got back a confirmation e-mail that said their typical response time was currently six to ten business days.

I'm not sure if you actually mailed a letter from Isreal to their Houston, TX address or e-mailed. If you didn't e-mail, I suggest you do so or fax a copy of your letter if you still have a copy. This will of course reduce the response time.
