I ordered a rather heavy cabinet (28kg). When I saw that dpd would be the deliverer, it was already clear that it would go wrong. At least the doorbell rang. Before I opened the front door, I asked the gentleman about the doorbell whether the package would be very heavy and whether he could help me carry it. He claimed the package was 15 kg and put it down in front of the "Abstellort" (which was not specified by me) mailbox and he was gone. At dpd, parcels are NEVER delivered to the apartment door, but only to where the respective messenger wants to. Why actually!? !!?
I live in the rear building on the 3rd floor and I am alone. Now I wanted to get the package. Several stickers say "caution> 15kg" and that the package weighs 28kg. You can tell whether something weighs 15 or 30 kg !? I didn't manage to carry the package into my apartment by myself, now it's standing around in the stairwell. Thanks for nothing dpd!
For me, dpd is by far the worst delivery company in Germany. You experience this again and again. If you could give minus stars, you would get them all !!!
