Looking at my jouney statement I see:

11.54 Bus journey route 149 £1.50
11.54 Unknown transaction £1.50

What can trigger this at the same time and what's it for? I assume it's
an error.

Not seen that one before. An immediate retouch with the same card
should be rejected and no charge made. Most odd. I assume there was
something wrong with the reader or did you have a second Oyster card
or bank card near your Oyster Card? Not sure if "card clash" related
issues could cause this.

I assume you've requested a refund.

It is an odd one. It was actually my wife using my card as she had just
lost her own card - I have just asked her what she did and she just
offered up the card alone, which is in a plastic holder. She doesn't
recall a reader problem (it was 6 April). Her purse was separate so I
doubt it was a contactless card conflict which in any case would be for
a different account.

I have just filled in the online form to register a refund/complaint.
