Re. anon card and DPA
I had a most enjoyable experience with customer service (CS) re. unauthorised charges on an Oyster card (if you use pay-as-you-go, CHECK THE CHARGES FREQUENTLY as the system gets it wrong *often* - unsurprisingly never in your favour).
Conversation (phone handed to me by guy at ticket office):
Me: "Hi, guy at ticket office tells me you alone can correct charges, here is the card number"
CS: "Umm, yes. That card is unregistered. We need your name and address.
Me: "Why? What part of 'unregistered' doesn't work?"
CS: "We need to make sure we pay back the right person. You could have just found the card."
Me (after finishing laughing): "And by which process would you make sure that I didn't find it when I give you my details now?"
CS: "Umm. Umm, it's part of our process"
Me: "So the price of a refund has now been raised to my privacy?"
CS: "Sorry, we can't refund to an unknown card."
Me: "So, we now have set the price for privacy at London Underground. Well done".
Let me repeat what I said at the top: the Oyster card pre-pay system appears to err substantially in LUL's favour, at least in the case of two separate cards I've tried. Extrapolating that to the volume of cards out there it appears this is a nice way for LUL to earn some extra cash by making it difficult to recover erroneous charges.
This may also explain why the refund process is (a) now extremely well hidden - try finding a brochure about Customer Refund, or even more than a one liner in, say, 1 out of 30 brochures - and (b) it is not automated like it can be.
I would be interested in knowing just how often they have to correct charges. The true number could be rather shocking.. Anyone any idea?
PS: for the record, I still have those 2 cards, and I think that includes the journey printouts...
