I tried to purchase tickets on the voyages-sncf.com web site. The web site showed an error message, and I received no confirmation or reference number. But my credit card was charged by the merchant "SNCF TGV.COM 77 MI MITRY M". Later I successfully purchased the tickets, and so I want to cancel this transaction. The credit card company tells me that the merchant (SNCF) needs to cancel the transaction and send the cancellation invoice to my credit card company. I have the credit card transaction number, so what email address or form can I use to send this request privately to SNCF? The online reimbursement request form at http://www.sncf.com/en/services/customer-service/claim-form requires a "Référence Dossier Voyage", but I never received one, so I cannot use the form.
Thank you!
