Second email to apple.
One would at least expect a confirmation email right??
Hello Michael,
Corey here, I'm very sorry, but unfortunately I am not in control of the up-to-date program, and as such cannot assist you with your Up-to-Date claim in anyway directly. As I stated previously, you should receive a reply to your claim in the next 48 hours, which should either approve and provide you with your code or deny it, which will mean you'll have to purchase OS X Mountain Lion from the Mac App Store.
I would like to apologize again for any inconvenience this might cause you, Mick, and I sincerely hope that you will receive an answer to your claim soon. Please let me know if you have any other questions or concerns relating to your account and I will always be happy to offer you my knowledge and assistance. Please take care and have a marvelous day!
Sincerely,
Corey
iTunes Store/Mac App Store Customer Support
