I received a package from DPD today and I don't think the delivery is ok.
The driver rang the doorbell for me and a neighbor. The neighbor was a bit faster than me and pushed the door opener. The driver opened the door without comment and placed the package in the stairwell. Since I live on the first floor, I thought that the doorbell was wrong. If the neighbor hadn't brought me the package, I wouldn't have known that the package was there and everyone could have taken the package. And that's not an isolated case at DPD.
