My 26-30 railcard disappeared from the app on my phone after having to re-download the app due to low memory space. I rang trainline about this as I have a journey booked for tomorrow (Thursday) and return on Sunday. My tickets were booked with the railcard discount as before, I had a railcard. I was given some money off my tickets after mentioning several times it was not my fault that my railcard had disappeared from the app, was told trainline could not help me with this, and they told me they would give me money back from my tickets only if I booked new tickets at full price without the railcard - as I couldn't use it because I didn't have it to hand. I did this whilst the woman was on the phone, told her when I'd booked my tickets and realised that I had been robbed out of £97 for my new tickets and lost out on £30 because of my railcard disappearing from the app! Absolutely rubbish! I feel robbed! Before, my tickets added up to £63 altogether and I have not even been offered the full refund for those. Additionally, I thought to buy a new railcard whilst the woman was on the phone and this wouldn't load on the website on my phone or on the laptop, so I could not access this if I had wanted to. I think the system has been updated, hence why my railcard has been wiped from the app, absolutely terrible, I am feeling very angry and let down by this company and have a hospital appointment which was partly why I was making this journey and this has added more stress. Trainline only care about grabbing money from people and don't give proper customer care out. Additionally, I was on the phone 1 hour and 6 minutes, which is also money coming out of pocket.
