I will using contactless in London next week. These sections concern me from the update at
https://tfl.gov.uk/campaign/cyber-security-incidentOyster▸ and contactless customers - online journey history is currently unavailable through any of our platforms
We're currently unable to issue refunds for incomplete pay as you go journeys made using contactless, so always remember to touch in and out. Oyster customers can self-serve online
...so I have no way to verify what they charge me is correct and if it is incorrect then I wont be refunded?
