I signed up for the free tier of Google Cloud. I completed the entire process (phone verification, card details, address, cardholder name etc.) I chose account type as business instead of individual, because I want multiple accounts to be able to access the platform. It asks for a business name which I entered. I didn't give tax details though, because they were optional. Then I pressed the "Unlock My Free Trial" button after which it asks for CVV, which I entered. Even a transaction of a nominal amount was made from my account to validate it. But after this, it just goes back to the previous page (the form at the end of which was the "Unlock My Trial Button"), and nothing happens. My trial isn't started. Every time I click on the button and give my CVV, a nominal transaction occurs, but it doesn't unlock.
Am I supposed to give my tax details? Why could this be happening? Thank you.
