You can call the SNCF phone line on 36 38
, they will cancel your tickets based on its reference . Assuming you old that big old kind of tickets, not an e-billet or a regional ticket. Black and white, without a QR-code but with the mention à composter avant l'accès au train
, your reference are the six letters next to dossier
on the lower right corner.
Then you will need to return your ticket to a station or by mail to actually get refunded.
According to the French FAQ (wich has not been translated in english) you should be able to cancel any ticket on a strike day with no fee. Even usually-not-refundable tickets (like Prem’s) are refundable.
This pages says that you can even get refunded after departure times on strike days.
Good to know ; on strike, and if your train is cancelled, you can take any other train that goes to your destination without additionnals fees — even with non-exchangeable tickets.
Those details may varry from one strike to another, depending of it’s duration and geographical area.
According to the international site of SNCF, you can ask a refund via post:
To obtain a refund write to:
Service relations clients SNCF
62973 Arras cedex 09

It specifies that you need to send:
the original tickets if you have received them
your booking reference
your full contact details (full name, address and phone number)
Note that I haven’t actually tried this.
