I have activated my account but cannot get my gpu all regions increased?

I want to try two things in google cloud.

Nested virtualization to create bunch of simple office computers with gpu support (nvidia grid).
Premptible render nodes and AI training nodes , to work with some fault tolerant algorithms.

I have activated my account. Requested more GPU all regions increase. Mailed to the support. Tried to chat with technical support.

-- Mail delivery subsystem error. gc-team@google.com

-- Chat did not start, circle swirled forever

What should I do ?

Thank you.

Solution

As I have been informed, in some regions, google cloud prefers opening gpu's and some services through their solution partners. I have contacted sales, arranged a meeting. In this meeting, they redirected me to a solution partner. We signed a reseller contract, prices and services are same unless you ask for additional value-added support from local reseller. They gave me a sub-id and registered my company domain and e-mail to gcs. Everything works now.

Bottom line I get from this is:

If you wanna get serious with google cloud you may want to contact sales directly.
