Blue response please: (E-mail Question)

I posted a while back about an issue I was having with my old E-mail address I once used for my battle.net account. I've been getting the typical spam mail, which is annoying; but since I switched my account over to an e-mail I only use for WoW, I delete it all.

The typical e-mails include: the beta testing, account restoration, added game time, account being disabled, etc.

I check today and see I have another e-mail from 'Blizzard' stating that 'my' account may be disabled. I know it isn't becuase I stopped using this address when months ago when I took a break (changed e-mail address and password at that time)

Here's the e-mail I got:

If I'm reading this correctly, this is from Blizzard. All I'm asking is:

Is this a real e-mail from Blizzard?
And if it is, I'd like to know who to contact on getting this e-mail disabled prementantly from being used for any battle.net account.


Oh! one more thing, not related to this. I changed my name on this toon a while back, I was curious when it would update to the new one?




Thank you for your time :)
