Does anyone know why Oyster don't link Auto Top-up directly to a standing order/DD via bank accounts and only link to bank cards? I recently lost my purse and cancelled my debit card forgetting that my Auto Top-up was linked to it and not to my bank account. I was fined on a bus as I hadn't realised there was no money on my Oyster card. I called Oyster customer service line and the advisor, who also asked other members of his team, wasn't able to tell me.
