Assumed authorisation to leave an expensive computer with neighbor. Neighbor denies receipt of goods item now lost and more importantly I'm now behind shcedule with my business due to loss of important computer. Customer service was a waste of a whole afternoon. They said they had authority to deliver to any neighbor because I hadn't opted out of the deliver to neighbour service. The sender specifically instructed dpd to only deliver to myself at my address. Opt out system is hidden away in the app and as a reciever of parcels I had no reason to check the app prior to encountering a problem. Dpd have refused to accept any responsibility for loosing my parcel as they claim they were autherised to deliver to any neighbor.
