DHL does not handle end-to-end delivery
Although the package was initially handled by DHL, it was ultimately the postal service that was responsible for delivery. I heard a letter being placed in my mailbox. It was the mail carrier slipping in a non-delivery slip due to absence. I checked, and the doorbell was working fine. So, he didn't ring, and I had to go to the sorting center to retrieve my package; otherwise, I would have had to wait until the next day for a redelivery.
