I do not know about everyone else but I am tired of the CANNED responses from Norton on Identity Safe.  Such as "We are working on it and we will let you know when nit is available" or " It will require a big fix and our programmer's are working on it. 

 

I WANT THE FIX NOW I'VE BEEN WITHOUT IDENTITY SAFE FOR 5 MONTHS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
