Google Support is not easy.
But I wonder if it is because Anthos is not right for your company, it is primarily from my understanding companies with big VMWare setups and the price for Anthos is heavy.
Why will you want to use Anthos? I was at the Google Cloud Next where it was announced and was also excited, but asked a lot about from my closer Google relations and it was not something for the public was my learnings. Very complicated, heavy and expensive.
