Unfortunately, I lost my BahnCard 25 for 2017 (I still have the 2016 one, though). Can I get some kind of proof of purchase of the 2017 BahnCard in the ticket offices to show to the ticket inspector?
I know I should get a new one, but it's too late for that since I'll be needing the card next week and they take more time to make and send a new one, plus they don't answer my mails sent to email@example.com and also it's a card which will expire next month, so it's probably not worth it to pay 15 euro for a replacement at this point.
So how can I produce a proof that my Bahncard is still valid while not having the actual card? Can I get such a document at the ticket offices in the stations?
