Google Cloud Platform - Trial fails to start

I am trying to start my trial for a Google Cloud Platform for a week.

I reach step 2/2 of Account Information and complete the whole payment process. Even money is deducted from my bank account multiple times. But the process doesn't go through. After the payment is collected by Google, I am still on step 2/2 page.

I tried clearing cookies from my browser. Also tried contacting the support at Google but found no way to get in touch with them.
