Parcels were simply placed next to the front door. There was someone at home.
The delivery person was even notified of the 3rd floor via the intercom.
Filing permission is valid "in front of the apartment door on the 3rd floor" and not next to the front door.
DPD is by far the worst deliverer in the area.

UPDATE 08/29/2020
Today a package was simply deposited on the stairs on the 2nd floor.
Despite a complaint to DPD, nothing has changed.
