So, I was on vacation for around 12 days, and came back last Saturday (4th November). In my mailbox there were two yellow slips from post.ch with 2 registered letters, with the pickup latest on the 3rd November.
I took the slips in the hope of the letters still being there, and went to the post office today (Monday the 6th November). The lady said that the letters were returned already and there was nothing to do, I said "Schade", and went back home, she threw the yellow slips away.
Now I started to worry since a friend told me that in Switzerland, if you don't pick up a registered letter - it is considered _delivered_. It might have been something important, I have _no_ idea. I didn't think about this at the time, but I should have checked the track&trace numbers from the slips online and I could have seen the senders of the letters, I didn't think about this earlier, and now it is too late.
Usually, the authorities in Zug where I live do not send registered letters, so I hope it's nothing that needs a time-sensitive reaction to authorities - I also hope that they would resend the letters again ?
Did anyone try this kind of situation? I plan to go down to the post office again tomorrow morning and see if they are able to look at my name/addr. in the system and see the historical senders - not sure if that is possible or legal re. privacy laws, etc.
As a better-safe-than-sorry measure, I plan to call my local tax authorities to see if it might have been something from them, tomorrow.
Any tips on what I can do in this situation - and maybe also any experiences WHO actually sends registered letters in CH? I don't have any debt, or unpaid bills (as far as I know at least), so I'm a bit baffled.
