Query: broke

I was very happy with this product until it inexplicably stopped working 3 months after the 90 day warranty ran out. It will still beep to wake me up like a conventional (read-irritating) alarm clock, but it no longer plays music from, or charges my ipod. Im really disappointed that the warranty is so short since Id sure like to get my money back.
