I use Android Pay for all my commute in London. TFL applies an automatic cap for daily and weekly journeys depending on zones etc…
Last week I started with Monzo Android Pay but then for one journey touched the wrong card. I had been showing someone card features in Monzo app and had disabled the card so Android Pay had changed my default card. Anyway, I was charged £19 on Monzo and £7.80 on my other card. Got in touch with TFL and they added the missing touch-in on Monzo and told me there will be automatic refund back to the card and the daily cap also be applied automatically. It indeed happened as they said but in a little different manner - Android Pay shows a refund transaction of £19 but there is no correct charge transaction there. I was charged £11.20. I am sure this is how TFL/Android Pay integration works but I thought it was bit weird.
For the 2nd card they asked me Sort code and Account number for a manual refund, I gave my Monzo details again refund was processed in 3 days but it’s like this;
I know again this TFL’s 3rd party processing so details look weird but maybe Monzo could make them look bit better on the feed and integrate these with TFL history…
