There seems to be some misunderstanding or miscommunication about the method of delivery.
At first, you gave the impression that it would be delivered by courier:
"the delivered luzern rail passes in engelberg before my arrival"
"They said that the courier was delivered before my arrival"
Then, the email you received from them indicated it was sent through the normal mail, and they did not know whether it had been delivered or not, only that it was in fact sent:
"They were sent to the address you've mentioned with the attention to you by regular post on the 4th of May. The post always takes about 1 week to arrive in Switzerland, therefor it should have been delivered."
Courier delivery and normal mail delivery are two different methods of delivery. The fact that it was sent by normal mail, and wasn't expected to arrive until 11 May makes it more likely that it is still on the way, rather than having been incorrectly delivered. Your first post about the lack of delivery was on 9 May, two days before delivery was expected.
I hope it turns out well for you. Let us know what happens.
