Hello Coinouyeaqu40
Can be, I am a ticket professional and not that much into internal processes around luggage shipping service.
Important is that you have got a number, so the case is definitely filed. And, in such case, writing is advisable, to track down the entire discussion. I hope there will be a resolution to your problem soon.
Please let us know about the outcome, we are eager to know. It helps us to give advice to fellow customers being in the same situation. Although I must say, it is the first time in 10 years working with SBB that I have heard about a lost property, that was lost while shipping. Not so with airlines, as I experienced in my former profession.
Best wishes,
Roland
