Query: Worst customer service ever!

I got a LS3700 with 2221 songs ( LS-2953BP Backpack Combo) and I've used it few times and after not using it for few months I turned it back on and it wouldn't. LS3700 microphone broke so I've been trying to contact customer service to get it fixed cause it's an expensive item but if you goto their website, there is no contact phone# or email. They have a form where you can submit questions but they will take over 2 weeks to respond. It's not worth it!Their karaoke machine scores on if you put sound through the microphone the whole time. And they dont even have movies for the background. Just slideshow of pictures. It's not worth the price.
