New Wii U Blinking Blue Light

Hello,

          We got a Wii U Deluxe for Christmas, hooked it up and all it does is blink the blue light. I’ve tried calling the support line but never get a person, the recording tells me to look at the online support and the online support and it tells me to call. Should I keep calling or simply return the Wii U? I would try to exchange for another, but they are currently out. 

Any help would be great.

Thanks.
