My best advise is to reach out to office of the president Roger's communications.
My best wishes for you to resolve the situation.
I don't understand what you mean when you say "Do you remember if you got a email or a actually copy of the upgrade to the device?"
I was sent an email that had instructions on how to unlock my iPhone. The email had my phone's IMEI in it, but not the purchase information.
If I had the original proof of purchase, I wouldn't be asking for Roger's help. Obviously it would be better if I had not lost it.
I don't need the whole contract printed, just something that connects my name to the IMEI, so that Apple knows that I own that device, specifically.
Thank you for posting your concern in the Community. We can only resend the Proof of Purchase for the most recent IMEI on the account.
