I can definitely imagine your frustration and disappointment. This is certainly not a good way to start your holidays! Regardless of who's right about the ticket price, it seems that some railway officials did not exactly respond as helpful and polite as you may expect them to. I know how personnel can sometimes react in popular and busy tourist locations, but of course there's no excuse for that.
Now, about the tickets: I didn't know that special offer, but probably this is the one
you are talking about right? I don't see the ticket copies you said you attached to this post.
From what I understand from your post, a couple of things went wrong here:
1) The Jungfrau Railways grant a 50% discount to holders of various passes, including the GA (for other readers: that's a "General Abo" providing unlimited traveling to Swiss residents). The Jungfrau Railways grant a 25% discount to holders of a Swiss Pass. You can verify that on the map we link to from the Swiss Pass page
. The discounts go into effect from Wengen or Grindelwald. You can travel for free to either of these villages.
2) The tickets you eventually purchased cost 48.00 + 49.50 = CHF 97.50 per person. This amount is not listed for the special offer. They list a price of CHF 94.80 for GA-holders (which is not valid for Swiss Pass holders). So I wonder if you actually got the special offer, or just discounted tickets for the ride, and not including the cheese fondue discount. Discounted tickets (50% off) for the legs you mentioned would cost 48.20 (Lauterbrunnen - Jungfraujoch) and 49.00 (Jungfraujoch - Grindelwald). These prices are listed on the Jungfrau website
The tickets that should have been issued along with your Swiss Pass are tickets Wengen - Jungfraujoch - Grindelwald with a 25% discount. The price for those, according to my best knowledge, is CHF 126 per person. I don't know whether the special offer can be combined with the Swiss Pass at all.
Like you said: you did in fact get an underpriced ticket. I wasn't there when those tickets were purchased, so I don't know how that could happen. I feel sorry for you that this is what happened, as it obviously caused a lot of confusion, which may have drawn the attention away from a magificent location such as the Jungfrau. That's the last thing you want on such an excursion.
Regarding compensation: You wrote "we request you to kindly give us some compensation". Are you addressing this to us? You may not be aware that this website is not owned by the SBB, the Swiss National Tourist Office or the Jungfrau Railways in any way. We're a website made by tourists such as myself for tourists such as you. I can only recommend to contact the SBB Customer Service
through their contact form or by writing a letter.
Thanks for sharing your story! We like to hear about anyones experience, whether it is good or (unfortunately) bad. I hope you were able to enjoy the rest of your holidays, and that, inspite of this problem on the first day, your Swiss Pass has offered value for your money after completing all your 8 days of traveling. I also hope my answer helped a bit to explain what probably happened and what you can do now.
