I wrote on the 17th January:

I've only recently started using Oyster PAYG on a semi-regular basis. I
topped up on Tuesday using the FCC ticket machine next to the ticket
office at St Pancras International. I have a couple of queries:

(1) The top-up location on my journey history is shown as "Bus". Why would
that be?

(2) I noticed that the machine showed that the Oyster card was loaded with
a Zones 1-4 Weekly Travelcard for a specific week in 2007, and it offered
me the option of renewing it. I have never had any Travelcard loaded on
the Oyster card, indeed I've never used any kind of Weekly Travelcard. I
did wonder whether this situation is in some way related to the fact that
this particular card was one I obtained by post (to Retford) during the
short period that 'free' (i.e. without £3 deposit) cards were on offer. I
can't remember when that was - perhaps 2007? I think that at that time
only cards with a Travelcard loaded were normally issued free, so did TfL
load an 'expired' Travelcard on all those free Oyster cards?

Later in that thread, I promised to post details of any replies I got to my
queries. Sorry it's taken a long time; I've been waiting in vain for a
reply by TfL to my email, but I needed to phone the helpline anyway today,
so I repeated my questions. None of the replies has turned out to be very
illuminating, but at least my call was answered very quickly...

Answer to qn 1 above: The Top-up location just appears as a reference number
on the system the helpline operative was using. He agreed that "Bus" was
incorrect. (Presumably someone has failed to link the reference number for
the FCC machine at St. Pancras to its actual location, so it defaults to
"Bus", but why?)

Answer to qn 2 above: "It shouldn't happen". "Just ignore it".

Qn 3: Why is nothing ever shown in the "Price cap" column in the online
journey history? Answer: just ignore it.

Qn 4 (the actual reason for my call): My online 'card overview' shows a
PAYG balance of £5.71, but in the online 'journey history', no transactions
are showing after 10th February, at which time the balance was £11.21. Why
aren't my more recent journeys showing? Answer: Would you like an email
showing your recent (March) journeys (details of which he read out to me)?
Yes, I said. As a supplementary question, I asked whether these journeys
would eventually appear online, but I didn't get a particularly clear
answer.

Living 140 miles away, I don't use Oyster all that often, but I'm still a
'supporter'. However, this list of queries and the responses lead me to
believe that things are still somewhat shambolic. Is that a fair
assessment?
