There are a number of reasons your payment method has been declined, including a typo in the credit/debit card details, an expired credit/debit card, the daily spending limit, insufficient balance, etc.
You can check the transaction status as per below:
Click on the "Plan & billing" tab, which can be found in the dropdown menu in the top right corner.
Scroll down to the bottom of the page to find your billing history.
If the transaction was unsuccessful, it will be marked as "Pending".
You may add another payment method or contact your bank or payment provider for help.
We will automatically retry the failed transactions a number of times over the course of several weeks before finally closing your account.
