I ordered an Oystercard online on Wednesday pm. On Thursday morning (9am)
I was sent confirmation that the card was despatched.

However now, on Saturday morning, no Oystercard in the post, and it's due
to start on Monday. Generally I leave the house for work before the post
arrives, so it is unlikely to have arrived by the time I need it.

Has anyone else had experience of what to do? Do I buy a normal ticket and
claim a refund? From a ticket office / online?

It's probably been delayed in the post but keep any tickets you buy and
ask for a refund form.
