A few years ago my package never arrived. DPD, on the other hand, referred me to the vending machine voice that my parcel had been successfully delivered to a neighbor. The name the voice called did not exist in our house. I went out empty-handed.
The delivery via email was announced today, I was at home. The doorbell rang, I got up, stepped out and answered with a "hello" (live on the first floor), but no answer, just heard that someone went out through the front door, only later did I understand that it had to be the messenger. This really annoyed me. You ring the bell, it is opened and then nothing more ?! By chance I discovered the parcel on our mailboxes. If the deliverers want to avoid contact, they can at least say "Hello" and where they put the parcel. So really ..
Someone wrote that DHL could cut a slice of them .. I've never had any problems with DHL.
