I've just had an email saying my pay as you go Oyster auto top-up
failed
(on W15 bus) on Friday because it couldn't charge my credit card. But

I've just logged in and resettled using the same credit card. What
gives? It's worked fine for six or so auto top-ups before and the
card
doesn't expire until next year.

The only thing I can think of is that on Friday I made a lot of
atypical
journeys in the east end - could it be some anti-fraud algorithm?

I think it has been mentioned here that most things that happen on
buses are done as a batch when the bus returnes to its garage.

Thus this may have been the first time auto top-up was done via the bus
or via this garage ?

Even if it wasn't some new bug may have been triggered.

As in all "card said to have been rejected" cases, I suggest you call
customer help at your card issuer and ask. They should have the
information on a screen in front of them. If the issuer denies any
rejects Friday-now, ask TfL what happened.
