I have been through the same problem last month. My Magento 1 extension had been in Technical Review for a month so I tried to contact Marketplace Team through contact form. After about 2 or 3 attempts from me, there was still no reply at all.
My extension was just going live a week ago, which is one and a half month since Technical Review (after Technical Review there's a short period of Marketing Review).
So I guess the best we can do is patiently wait.
