All may not be lost!!
If you're still in your 30 days take it back and exchange it.
If not, try booting into recovery mode and reset the phone. I don't think you need root to do that much and it should put the phone back to the way it was when you took it out of the box.
Hold down the volume button so that you are pressing both up & down volume at the same time (easiest to do with the battery cover off).
While holding the volume keys down press and hold the power button too. When the Samsung screen comes up release both buttons. A couple seconds later you will see the "Android system recovery" screen.
Press the volume down button until you have highlighted "wipe data/factory reset".
Press the "Home" button to select it.
You will then be told to press the volume up button to wipe the phone or press the volume down button to exit/cancel. Press volume up and follow any additional instructions. That's as far as I go to guide you (I want to keep my stuff as is
If that doesn't take care of the issue then you should take it to verizon and tell them what happened. Good luck and let me know if this worked for you!
