Shadowfoot:
Some banks will allow recurring transactions to be processed on a card after the expiry date. Some businesses track the expiry date and ask the customer to update their details.
The card hasn't expired, but something in the 'banks' system allowed one to be processed and the other not to be.
I am now told it will be 1-2 weeks before the card is manufactured and couriered to me. Fortunately, they have at least come to their senses and provided me with the details I need to continue using the card online and I have been able to book my travel. I'll have to use cash or my travel card in real life until then... I'll sort out the missing reward points later.
The ironic thing is, they gave me the details over the phone, not via their secure messaging system. So much for security.
