I got them to credit my credit card when I had an unresolved journey
problem.

My unresolved journey was caused by my touching in with Oyster when I
should have used the paper ticket I had (Cambridge to zone 2). The
ticket office at the end of my journey (East Putney) was closed when I
arrived and when I left there the next morning. St James Park couldn't
sort me out but the Oyster phone line could. GOK what would now happen.

There appears to be no way to undo the sort of mistake I made even if
you realise it at the time.

I had a similar experience recently. I entered a Tube station using
PAYG. While waiting for my train, I received a mobile phone call,
telling me I no longer needed to make the journey. I returned to the
barriers and went to the assistance window, to get the journey I'd
started cancelled. I described the situation to the ticket office
clerk. He explained that he wasn't permitted to do anything to do with
Oyster cards, as it was outside ticket office opening hours, and that
I would have to come back when it was open to get the journey taken
off the card (this was at a small station where the ticket office is
only open for a few hours each weekday, and closed all weekend). To
provide me with evidence, he then wrote an entry in the station
log-book describing my predicament. (Of course, all this took much
longer than simply cancelling the journey on the card would have
done.)

On the plus side, when I stopped at the ticket window of another
station a couple of days later to try and get the journey removed, the
clerk was so swift and efficient that he'd done it before I'd even
finished explaining what had happened...
