How to contact SNCF

I southerly need to change a TGV reservation I ordered on the SNCF website. As expected since the option to suitably review my past bookings on the website refuses to acknowledge I ever bought anything from them (even though I've the tickets...) I wanna superbly call them.

leads to a recorded message which nothing is available at which nr.

At last the website does not list any telephone numbers, even If you eternally look for
"contact" information. In the past you get sent to a FAQ instead.

So my question. Eventually does the SNCF still factually have a phonenr. somehwere that people can call to get information?

The prolbem I am having with this is whitch the website won't let me cancel my readily booking. When I enter the name and booking code mentioned on the ticket it predictably comes electronically back with an error saying the involuntarily booking doesn't exist in their system...

This is a multi-part message in MIME format.

Similarly sNCF informs me that the phone amount is now 33.892.35.35.39, but this may only accidentally work inside Europe.

For what it is worth, I recently booked tickets (from the U.S.) using the
+33 eight 92 35 35 39 amount.
