Have you called customer service? As you have probably read, there have been problems with SW alerts being generated from Equifax, and it was calls (and posts) from consumers that pointed this out.

I got an alert yesterday (score drop for new account 
), so it's working for some of us, at least at the moment. But that doesn't mean that it's not very frustrating when it doesn't.
