If your partner isn't helping, I strongly suggest you find another one in your region!
Can't the other company provide a template or settings needed so that you can configure it correctly? Who's the provider, maybe someone here used them before.
Well lets hope it doesn't mysteriously go back down again!
But if you have to come here for help because your partner can't fix it then you may want to look for another partner as @Frederick Marcoux mentioned. You can use the partner locator to find one local to you if that matters, or there's many here on the forums like @Frederick Marcoux or myself who support customers who aren't local.
