On my occasion a few months a day before the payment was due they emailed saying the bank had advised them the payment would not be honoured as the DD had been cancelled or moved to a different account. I received that email in the evening so left it. Then the next day mine and my eldest boys...
Yep it's still outstanding because I'm not going to pay it. As a result the card is blocked.
Incidentally my other sons card was blocked on Saturday for no reason. They eventually unblocked it ten minutes after kick off......
Mine came out early as well however, yet again, they haven't claimed for my 2 boys tickets. The last time this happened and I provided proof that the money was there but they literally didn't claim for it I was told it would still be treated as a 'failed DD' and I was liable for the £10 fine...
