Hi, Samih. I'm Augusto from the Atlassian Team.

I've checked your account, and it seems the issue was related to your card.

Can you please update the credit card information?

Update the credit card on file

To change the credit card being billed for your Workspace:

1. Click the Workspaces dropdown option from the top navigation bar

2. Select the Workspace

3. In the sidebar, click "Settings"

4. From the dropdown options, click “Billing”

Click Change in the Payment Method section and add your new card’s details. Only Workspace admins can update the credit card.

Let me know how it goes!
