It was just a slip of paper: DPD was there and you...

It was just a slip of paper: DPD was there and you should scan the QR code. I have made. Then I got the information that my package is somewhere abroad.
Pure stress. Today my neighbor came to me and asked me when I wanted to pick up my parcel, it was up to him. I could not tell from the information in the QR code that my package is next to one of mine. What the hell is the problem again, to write briefly on the slip, with which and given, as the post does. In my view, this company doesn't even deserve a star. I imagine service differently.
