hi, I am building a 6 x 580 GPU with msi h270 arctic, My first attempt failed, the mobo only recognized two GPU. what should I do?

Hello, I bought 5 days ago 07 / jan / 17 an antminer s9, but I have not received any response from asicminermarket.com I wrote on the page contact us on 10 / jan / 17 and to the mail sales@asicminermarket.com on 11 / Jan / 17 and I do not get any answer. 5 days without any contact, does that seem normal?
