"Your Apple ID has been disabled"

I got an email from “Account services” that says “Your Apple ID has been disabled” although I can still log in here and for testing I got a free app from the App Store. The email says “Due to a problem with your card” and a bunch of other text that suspiciously will not copy and paste. The email says to go to https://appleid.apple.com to unlock your account.

Is this legit?
