Please allow at least 72 hours after an auction is ended before contacting use about items not being received. After that time has elapsed, you can submit a support ticket as described below:
1. Go to the Battle.net Support website at https://us.battle.net/support/en/ticket/submit
2. Choose "Diablo III" as the game with which you need assistance.
3. Ensure that "Use a few words to summarize your issue" is selected.
4. Type in "auction house" and click Next.
5. Choose one of the options that best matches your problem.
6. Scroll down to the bottom of the page and click "Submit a Ticket".
7. Fill out your ticket and click "Submit".
I do see it in the account's info and the item was won as described. It's probably just going to need time before it's sent. There's really nothing we can do about auction house transactions here in the forum. Submit a ticket as I mentioned above but only after waiting at least 72 hours.
