Nothing but trouble with DPD. Despite signs with arrows indicating where to ring, no delivery, even though you are at home, the package will be returned to the sender. Or there is a short bell and then the package is placed on the street, no answer via the intercom. Just get in the car and dash off. It's been like this for years. I can throw up when I see DPD delivering after ordering. Unfortunately, the drivers are also not proficient in the German language, and they are also unfriendly and stressed. I tried, but at some point it's over.
