Your payment might have failed or been declined for these reasons:

You don't have sufficient funds in your nominated bank account on your payment date.
Your card has expired or been blocked.
You’ve cancelled your recurring payment.

Here's how to update your payment details:

Sign into your Belong account using your username and password.
Select the Payment option at the top of the page.
Choose Add/edit payment method.
Depending on your method of payment, select either Mastercard/Visa or PayPal and follow the prompts. If you select PayPal, you’ll need to have your login details handy for that account.

What happens if your bill doesn't get paid?
If your bill continues to go unpaid your service will eventually be restricted, then suspended and then finally disconnected. For more info check out What happens if I can't pay my mobile bill?
