It's been two expansions ago since I played WOW, so imagine my surprise when I check my e-mail today and it says I pre-purchased the new digital expansion for $70. A subsequent e-mail says the purchase didn't go through, probably because the credit card number was out of date. The e-mails appear legitimate; no weird hyperlink addresses or anything. Nobody in my household could have done this.
I did log in to Battle.net just now and it didn't show anything in my order history, but I'm not sure it would.
I was playing StarCraft 2 within the last few weeks and had to log on to Battle.net to install and play it.
So... now I have some suspicions/fears, but figured I'd ask around and see if someone more knowledgeable about this kind of thing can tell me what's going on and what I need to do about it. Thanks...
