I bought trial bahncard for 3 months on online, but it seems like I couldn't get the physical card because I'm not sure if it will be delivered before my trip to Germany. I know I can use the temporary PDF or the digital card on app, the problem is my app doesn't show the bahncard somehow. My friend's temporary card have show up on her app so she might just wait until the temporary card is given the card number after the production(I read it somewhere). But I have no way to check and I need to register on app with the bahncard number which I don't have. I need to use the card after the validity of PDF and cancel the renewal. DB email services keep not replying to my email. What should I do?
