In regards to somebody saying it might be the "fork lift driver", he had a tag on that said "Scott - Customer Service Manager".
I called the 1-800 number for Walmart the second they opened and some 60 year old woman picked up the phone, did the "oh my, I understand" 50 times, wrote down everything I said, and told me I would hear back within 3-4 business days. She said it was forwarded to the Store Manager and the DM. Now, if I was this guy, I would just say "that never happened" so I asked the woman what my options were if I wasn't satisfied with the outcome and she said I could call back as many times as I needed and they would keep going up the food chain until I was happy. So I guess we'll see what happens.
Edit - Yes, I still have the receipt for the game and pictures of the case, but they were taken AFTER he had already messed with it. Funny thing is, even though he ripped it even more, it's STILL not that bad and there is STILL no way I could have taken the game out of it. I'll post a pic in a second.
