Never can I remember a case when DPD would properly deliver a parcel. Either they don't even bother to ring the bell and leave it somewhere on the floor by the mailboxes where it can be picked up by anyone or they leave it with someone else (while I was home waiting for the parcel) and not even properly notifying who has my parcel.
The absolutely worst delivery system ever!
