My personal two cents: They refused to send my an invoice, so I didn't payed after their auto-removal on time. I did pay later. Then they send me to some random collections company AFTER they received my payment, according to their own data. Now they refuse to hand out a ticket to me that I payed for. I needed to travel and had already bought a ticket that relied on the Bahncard. Therefore I bought a second Bahncard, because provisional Bahncards can be handed out by the staff directly, but it's not valid for the whole direction I bought it. I expect them to still refuse to hand me my ticket and they also didn't confirm that I canceled my first Bahncard.
