We posted a link to a non-official support site that we probably shouldn't give attention to. Anyway, please don't give your information to anyone other than http://help.minecraft.net .
I'm sorry for any trouble you're having right now! It's currently a temporary issue we're looking into. I would check back in later on and keep an eye out on https://twitter.com/MojangStatus for any possible updates. Thanks for your patience! ^AS
