Game is stuck in Wii U

There is a game stuck in the Wii U. It will play, but will not eject. When I press the eject button you can hear it trying to eject the disc, but will not spit it out. I have tried holding the eject button in for a various lengths of time. I tried holding the power button in, as well. I have also unplugged it for several minutes, and tried again. Any ideas on what I should do?
