I had one of the issues with the Up-to-date codes and went through receiving 3 codes like most others did. I replied to the email when I received my 3rd code and it worked. I inform the lady that was following up with me to make sure everything was taken care of and I told her yes the code worked but I had already purchased ML because of the wait time. I did not ask for a refund nor acted mean towards her. And thanked for her for the help in the matter.

So i ended up received ML and ML Server for free altogether. Not a bad deal. I think Apple knows they screwed up on this one.

Dear Aron,
I understand that you are entitled for a free upgrade and decided to purchase the "OS X Mountain Lion" from the Mac App Store instead of claiming your free product code.
Aron, I acknowledge the importance of this matter. As an iTunes/Mac App Store customer myself, I can appreciate your concern to make sure money is accounted for and spent wisely. Don't worry, I will be glad to help you with it.
After reviewing the circumstances of your case, we determined that issuing you a refund for your unintentional purchase of "OS X Mountain Lion" is an appropriate exception to the App Store Terms and Conditions, which state that all sales are final. In five to seven business days, a credit of 19.99 USD should be posted to the credit card that appears on the receipt of that purchase.
I trust this information will resolve the issues you experienced. We always strive to create a positive iTunes/Mac App Store experience. Don't hesitate to contact us again if you need additional assistance and we will gladly assist you.
Thank you for being a valued customer. I wish you the best and sincerely hope that you will continue to enjoy shopping on the iTunes/Mac App Store.
Sincerely,
Anne
iTunes Store/Mac App Store Customer Support
