You suck Microsoft!

I guess doing a simple Google search was out of the question. Try to type Microsoft Zune Support and you should see the first link pop up as this here.
It's also it's own link at the top right of Microsoft Zune's own website Zune.net - "Support". Contact them and simply request a refund, they offer refunds to people who have
trouble with getting the videos started and of course if you were charged twice.

Have you attempted to contact support for this? You say there is no contact info but it can easily be found.

Xbox support support.xbox.com/contact-us or Zune chat support can be accessed from Zune.net

Please contact either of them and explain the situation, they may be able to help.

Why would you buying something twice? Just wait or call for help. It is so simple a caveman can do it. And by the way you have not been charged twice, you just paid for the same thing twice.

I'm about in the same boat but with my Xbox 1.

My XBox 1 was working just fine yesterday, and the day before and the day before with no issues. Power up today - oh hey there's an update, either apply the update or stay off-line. go to apply the update and guess what there's an error getting the update.
I know shocking.

Follow the on-line support - downloaded the OSU1 (Off-Line System Update 1) and applied. Still wants to do a simple 796MB update which it can't get.

Contact support - go through the steps - do a reset - guess what still wants the update of 796MB that it can't get.

Download and apply OSU2 - Ok. no issue. go to apply and the system says nope not happening.

Contact support again. This time do a full reset of the system as it's already been reset with files saved and stuck in a setup loop, what's it going to hurt.

GUESS WHAT NOTHING CHANGED - guess what you have to send the unit in to get fixed or take to an MS Store. Well closest MS store is Salt Lake City, Utah. that's 3-4 hours out. So what about sending it. Guess what You need to pay us $115 dollars not counting
tax to fix an issue that we created."

I fixed this by removing two factor authentication from my account. What a piece of cRPP security system, it doesn't tell you from the console this is the problem whatsoever. By the way, to do this, I had to use Chrome browser, because the Microsoft browser
says "There's a temporary problem with the service. Please try again. If you continue to get this message, try again later."

Microsoft, you'd better get your act together, or you're done as a company!

So in order for future services to work, disable two factor authentication, because it DOESN"T WORK on the XBOX console, nice job!!
