Is HomeGrown Audio still in business?

I placed an order late Sunday night for the DIY Silver Lace kit. I received the automatic confirmation email. Since then my card has not been charged and no further emails from them.

I tried to call the number on their website but was told the number has been changed (by operator). Called the new one but it just rang and rang. Emailed them yesterday, still no response. Does anyone know what is up? Is this their usual conduct?

Thanks
