This is weird since I haven't sub'd to Live in several years with either account I've had! I didn't click on anything in the email but went to the website myself.
I had to recover the password, since I couldn't find it, so I don't know if someone had hijacked my account and changed the password. Recovering went normally, and clearly my correct email for that account is still on record.
I clicked on the icon for the notice but I don't see a way to dispute it. In fact, it says I have a perfect history. WTF?
Then it says something about communication elsewhere.
I'm guessing someone has figure out out spamming messages on Live and using innocent gamertags in the header so they get the blame.
