I got total of 18 scam mails from them... 3 of it are this but credit card type is Visa which they got it right. The rest of the emails are violation, username change and others related to WoW and battle.net. Just ignore them.

Oh and nowdays every cdkey comes with combination of nums and alphabets.
Last tip which some ppl might find it useful. Even if u see links with, let say www.worldofwarcraft.com/account or www.battle.net in those emails, dont click on it. Try to move your mouse cursor over it. Most of the time the actual/real link that show on bottom of your browser is diff. Be aware.

And lastly, blizzard mail dont send by hotmail.com....
