Confused about upgrade to Norton Security Deluxe

I had Norton 360, used on two Macs.  I was told that it has been replaced by Norton Security, so bought the Deluxe version, and upgraded.  I spent several chat sessions and a few phone calls trying to get the subscriptions fixed--then, got told that I didn't need to upgrade, that Norton 360 was as good as Norton Security Deluxe.

So...now I'm confused and out money.  What's the real scoop?

Thanks.
