Would leave minus 5 stars if I could. Trying to get your money back from this lot is like trying to get blood from a stone. I used two separate contactless devices to touch in and touch out during my travel to London not realising that they didn't connect up even though linked to same card. Was overcharged by a substantial amount and provided the evidence via screenshot of my Google Pay Account. Wasn't good enough. They kept emailing me with question after question. I've given up now. They also overcharged me on a day when my train was delayed and I can't seem to apply for a refund online. Getting an error message asking me to contact them. Forget that!
