I know this is a long thread, but the answer is in it as least three times.
As far as I can tell, if NowTV cannot take a payment, they will wait a while (24/48 hours) and try again automatically.
I have gleaned this from the issue where money was taken from Monzo Bank customers, but NowTV gained the impression that the payment had failed and so took it again a day or two later, but did not try a third time. (Though this may be because they were alerted to the problem by then, I don’t know).
But certainly, once things have gone beyond a certain point, NowTV stop trying to take the money, and freeze the account.
