I'm following Google's instructions for purchasing Silver support, but there's no button or link for changing my current Bronze level of support to Silver. I think my appengine app has been integrated into Cloud Console -- I login to Cloud Console and I see my app. Also, on the appengine console, under Application Settings in the Cloud Integration part of the page, it says, "The project was created successfully. See the Basics section for more details." It doesn't offer a button for integrating my app with Cloud Console because, I think, this has already happened.
The instructions say to select my app in Cloud Console and then select Support from the left menu. The page I get tells me my current support level ("Your support package: Bronze"), but it offers no way to buy a different level of support.
Any pointers on how I can purchase support? I want to give Google $150/month for this, and they seem not to want to take my money.
