Let me put it this way: we stopped buying items from websites that use DPD. On a dozen of occasions they have failed to deliver and find our home (it is difficult to miss a 7-store high building). We came to know their level of competence and waited for them at the door, but they never show up. Their latest achievement: the driver drove past us without making an effort to stop, but we did receive the 'Oh-oh, we missed you' message promptly.
