Has anyone else had this happen to them. I have an annual travelcard for Zones 1 - 3 on oyster, and I topped up the PAYG balance online with £5, as I will need to make some journeys outside zone 3 in the next few weeks. When I touched in at my nominated station on Thursday morning on the way to work, my Oyster card was credited with £5 as expected. However when I touched out at the same station on Thursday afternoon on the way home from work, my Oyster card was credited with another £5. On checking my credit card statement however, only £5 was deducted from my card. Just wanted to know whether this is an isolated incident, or if it has happened before.
