"Battle.net Account- Account Change Notice"

I received 3 emails last night and this morning regarding my contact information being changed. I changed my password from a different computer, ran a virus scan (clean), and logged into my account where I found all my characters intact and safe. I checked my Battle.net account and my contact info is all in order.

Looks official enough. Was there a glitch last night? If I got hacked, it appears that nothing was affected.

Thanks in advance
