[The FINAL ROUND is complete!]

In this thread, I won a giveaway for a minecraft gift code from bitvegas: https://bitcointalk.org/index.php?topic=236304.

BitVegas promises to send me a Minecraft gift code:

The FINAL ROUND is complete!
Winning number: 4735 (SHA256 Key: "4735 wqlapIZKmubFPjkACGhW")
The winner: whatever69 with a guess of 5000

You will be privately messaged with your Minecraft Gift Code!

Remember you can now try BitVegas WITHOUT a Minecraft account over at bitvegas.net

5000

I have not received any giftcodes from him or any communication at all, and the giveaway has ended nearly a week ago.

If we cannot trust bitvegas with a simple free giveaway, how can we trust him to keep our bitcoins in our accounts in his minecraft server?
