I was very excited to receive an answer to my ticket today!
"Thank you for contacting Blizzrd Entertainment regarding this. I apologize for the wait, as you can imagine, things have been a little crazy around here lately. I have had a chance to go over the issue here and I think I can help. ^_^
Hey there! I took a look at your inventory to see if I could find this item for you. It appeared to be undleted but showed that it was in "bank slot 47623367". As I assume you don't have 5 million bank slots, I deleted the item and had it resent to your mail so that it wouldn't be lost. Good luck out there and happy looting! =)"
Can you imagine 5 million bank slots?? O.O
Thanks everyone for the responses!
