Got the same email. logged in and confirmed the same message was showing in my Account Activity which also showed the it occurred 10 hours before. I was also hesitant to call that number in email, so I went through the online chat to get a voice call back. The rep was initially confused about the message, but after brief hold was able to confirm the fraudulent activity. She filled out a form while I was on the call and stopped the fraudulent filing.
Yes the [phone number removed] number is legit. You can also call into the main support line [phone number removed] if there are doubts.
