Oh and it also appears that if you hold a paper ticket and want a DLR refund
you need to do it on a paper form.

You can only get the paper form from either a station listed below, or by
calling DLR customer services...

"Paper ticket refunds

Please call Customer Services on 020 7363 9700 from 08:00 to 20:00 for a
Service Delay Refund Claim form.

You can also get a form from Bank, Canary Wharf, Cutty Sark for Maritime
Greenwich, Island Gardens, London City Airport and Tower Gateway DLR
stations."
