I happened to see the DPD courier arriving at the window. He got out of the car and headed for the house entrance. Since he didn't ring the bell, I went to the front door, but he wasn't there, but drove away again with his car, not seeing a package. The parcel status is successfully delivered online. No package has been handed over to me or simply put on the doorstep without permission!
