I'm so fed up with the place. How are a company on the 3rd floor, basically the parcel is parked in the stairwell on the ground floor, in the parking lot or in front of the elevator, without notification or the like.
Or the parcel could not be delivered, with 100 employees in the house ... Deliverers cannot or do not want to speak German. We as a company no longer commission DPD at all!
