Bests & Worsts Reviews from Amazon

This item is not working properly. The timer and clock will not work. It just keeps getting hotter, the thermostat does not appear to be working. the timer will not work. I have tried to call Oster but I keep getting a message that "due to high call volume, they cannot take my call at this time, try again later" I need this replaced as soon as possible and am not sure how to get to talk to someone about it.
