Hello Hopwoodc
Welcome to the SBB Community.
We are a customer support page run by volunteers in their spare time, not the SBB Customer Service.
I can’t find any email confirmation of my 9 return tickets.
This sounds like the purchase was not successful.
Please call SBB, as we are unable to help with questions related to customer data, for data protection reasons:
+41 51 225 78 56 (24/7, waiting times may be possible).
You can also send a message to SBB with all ticket details, to ask for a copy of your tickets. A reply, however, may take multiple days due to the current vacation (festive) season:

Kind regards
