Hello, I have a question about making a reservation from bucuresti to budapest. We first made a reservation through the interrail reservation page, which led to paper tickets being sent. Unfortunately the tickets were not accepted by delivery and are being returned to sender now. We don't have enough time to reserve paper tickets again. We tried to reserve tickets through the Hungarian and Romanian railway company but then we have to pay full price (ticket and reservation) because we can't manage to get discount with our mobile passes. Is there someone who can help us with booking the reservation directly at the railway company? / Does anyone know if we can get these tickets at the Romanian (or Turkish, as we are now in Istanbul) station? 

Thank you in advance!
