It looks like the payment request has already gone through by direct debit, so from what you're saying I would assume this payment will fail some time soon. Once the payment fails the account will go in to a failed billing state in which you will have 14 days to make a payment for the outstanding amount, so you shouldn't lose your broadband if you pay within this time.
Having said this, you may run in to a failed payment splash screen, advising of the outstanding amount. You should be able to dismiss this during the 14 day failed billing stage by clicking "Acknowledge and continue browsing" towards the bottom of the page
