I finally got Apple Support on chat and they said: "I do apologize for the confusion. Your order and trade in has processed normally. This email was result of a technical error. We do apologize for the inconvenience but please disregard that email."
I mentioned it was very hard to get in touch with them, and they said: "Sorry we don't have any support email, but you are getting long wait while getting connected due to the technical error of that email which you received, likewise most of the customers received the same email."
A follow up email saying acknowledging the error would have been nice. As it is, it's nearly impossible to get an agent via text or on the phone.
