Najib Al Saddawi’s Query

Hello ! First I would like to thank you for a nice Prague in which I stayed five days. On the day of returning home , in Praha station, I waited in front of the monitor which showed the departure time and the platform. Just less than 20 minutes before the journey, the monitor showed that the train Nr.174 Praha - Berlin was on platform (6) . I quickly went there in order to reach my train, but when I got there , the information was not correct . I had then only a few minutes left to reach my train - what should I do ? But I was lucky that I found a train conductor who told me that the ( Platform ) has been changed to Nr.(4) Could you imagine how difficult for me as an old man was the situation ? I really would like to visit Praha again and if I will take the train the next time , so I ask you to find a solution to this problem . And I would also like to ask : Couldn't the one who was responsible for the monitor ,waited for another few minutes before he or she gave the correct information. Thank you in advance !

I can't verify my Yex account because the name on my ID card only has 1 word.

Reply: Thank you for reaching out. We understand the difficulty you’re facing with verification because your ID contains only one name. Please upload your ID as it is, and also provide an additional supporting document (such as a utility bill, bank statement, or government-issued letter) that shows the same name. Yex team will review the documents, and if further clarification is needed, they will contact you directly.

Hello, I have already made a reservation for the Sanyo Shinkansen through the JR-WEST Online Reservation system. The payment was successfully processed with my credit card at the time of booking. However, the credit card I used for payment will be cancelled (terminated) before my trip. I will still bring the same physical card with me, but it will no longer be valid for payment. My question is: Can I still use this cancelled card to pick up my reserved tickets from the ticket machine or counter, as long as the card can be physically inserted and recognized? I just want to make sure that the cancellation of the card will not cause any issue when I try to collect my tickets. Thank you very much for your assistance.

Reply: Thank you for contacting us regarding your reservation on the JR-WEST Online Reservation system. When collecting reserved tickets at a ticket machine or counter, the credit card used at the time of booking is required only as a verification tool. The system does not attempt to charge the card again at pickup. As long as you are able to physically insert the same card used for the original payment, your reservation can be retrieved and the tickets issued. Therefore, even if your card has been cancelled (terminated) by your bank, you should still be able to use it for ticket collection, provided that the magnetic strip/IC chip can be read and the card details match the booking record. If you have any concerns about the card being physically unusable (e.g., damaged, unreadable), we recommend bringing a printed copy of your reservation confirmation and contacting the station staff at the ticket counter, who can assist with identity verification and ticket issuance. We hope this clarifies your concern, and we look forward to welcoming you aboard.

Reply: We understand your concern regarding the missing reservation number and confirmation email for your Kansai-Hiroshima Booking Reservation.

Apple Pay に関して ICOCA カードサポートへお問い合わせしたいと思います。現在、ウクライナの Apple Store では ICOCA が利用できませんが、SUICA は利用可能です。ウクライナの Apple Store でも ICOCA を利用できるようにしていただくことは可能でしょうか。

Reply: Thank you for contacting ICOCA Support. We appreciate your inquiry regarding the use of ICOCA on Apple Pay. At present, ICOCA is only available for registration and use in certain regions and is not supported in the Ukrainian Apple Store.

Please be assured that we are continually working with Apple to improve our services, and your feedback has been shared with the relevant department for future consideration
