I've been finding it very difficult to set up a GCP account for over a month. I asked a few people around me for help, and they created new accounts, but they still ended up encountering the same error as I did. Meanwhile, I was able to set up accounts for Azure and AWS in less than an hour using the same payment option I tried with GCP.
Here is the error message: unsuccessful action
the action couldn't be completed.
This is frustrating most entry level GCP users.
