Posts 52, 62, 67 and 84 queried the OP travelling on a card for which they had previously applied for a refund of all credit. Did we establish that, before touching the card on a reader at the start of the journey in question, and notwithstanding the lapse in memory, the OP had previously attempted to ascertain that the card still held a balance available for travel and received confirmation it was?
When contactless payments came in I requested the return of credit on my 1st generation oyster card and was told most explicitly it was no longer valid for future travel and should be destroyed
