I got a response from support a few hours ago. It was basically a rehash of the KB article.
Then hopefully I'll be getting one soon. Let's see what they say to me. I'm getting a little tired of the stock response of "Have you checked the spam, promotions, and the box to recieve promotions" when I keep telling them in my initial letter I did all that. I know they have to say it, but dang it, it makes me feel like I'm talking to a wall.
edit: Over 24 hours later, and time for a status update.
Well, checking my email I still haven't gotten any response from the Help team. And that I actually sent my help request last friday, so we're at six days now. Nearly a week. Still got the higher than normal number of requests up on the help page. I don't know if they took the weekend, including monday off, or are just incredibly short handed now, but that's really bad. I sent a reply to the confirmation of recieving my help ticket asking about my situation several hours ago, but nothing yet. I don't hear from them by morning, I'm submitting another help request, and too bad if it's adding to their volume.
I've given up on getting the codes now, but I'll be damned if I give up on getting a response, and maybe, just maybe something actually done about this in the future. Honestly I'm more frustrated about it now than I would have been at the start of the week.
When they start the shiny box legendaries at Gamestop I think I'll try to pick up some extra to help out anyone who has trouble with that. You know, assuming they don't screw that one up and run out before I can get there or not send any to my Gamestop. After this, I figure I should try and help someone else avoid this kind of dissappointment.
Further edit: Well support got back to me, though it was the standared "Have you tried this?" steps, again. Which I informed them I had. Again.
Yet another Edit: And now they will be investigating my claim, and will get back to me within a week. So that's something.
