DPD is really the most unreliable parcel carrier I know. Today I was waiting for a package again. Again the information came by email that it was parked at the desired location and again that was not true. So I went looking for it like at Easter and this time I could actually find my package at least in the stairwell with the right house number (that was also different). Since I am liable if the package is taken by a stranger, it would be desirable if the drivers at least put the package where it is supposed to be (the desired location was on the ground floor in front of my apartment door) and did not unsuspectingly leave it somewhere. Customer service is unfortunately not interested in such feedback, as a customer got the feeling of being annoying. I usually don't order when I know that shipping is done with DPD, but unfortunately some sellers keep it a secret ...
