"Divorce" from the side of Russian Railways - what to do?

Question

Electronic commerce

The other day I bought a ticket for train 067 (Moscow-Simferopol), chose a branded reserved seat. Upon landing, I discovered that the light was not working in my compartment, and the upper part of the window was broken (which should open like a window). In addition, there is no drop-down curtain, which protects from the light from the window at night. “This does not pull on a branded car,” I thought, and discussed this topic with my neighbors in the car. It turned out that they had tickets for a regular, non-branded reserved seat (400 rubles cheaper). The conductor said “you bought tickets at the box office - contact them, I can’t help you with anything.” I kept the ticket with the indication of "brand name".
What can be done in this situation? I would like to somehow punish the carrier for such an obvious “divorce”, and even get some compensation myself. While I see options:
1) File a claim with Russian Railways
2) Make a chargeback ticket purchase through the PS (bought online using Qiwi Visa Virtual)
3) File a complaint with some other authorities?
Share, who had experience of litigation in such situations, as a better option, and what result can be achieved?

Answer 1

I would do this:
1) Claim to Russian Railways
2) Complaint to Rospotrebnadzor (now you can file via the Internet)

Answer 2

Make a claim by calling the hotline. A couple of times there were different problems, but by phone + a little time and the problem was solved in my favor.
