Query: Christmas - One year later

I wish I had read these reviews before I went out and bought the TYCO "Rebound" remote control car for my sons Christmas present. Now I can't find the battery charger anywhere and my son will be returning to his mothers without ever even playing with his Christmas gift -- (WON'T WORK WITHOUT A BATTERY!!!).I'm really angry about this and am very disappointed with TYCO.
