A year or so ago I ordered a left hand door mirror for SWMBO's car.
Despite being in all day when DPD were supposed to deliver it there was no sign of it and shortly after it was due to be delivered a note appeared on the web site saying that there was nobody in and they'd left a card. There was no card in our letter box. I reckoned that the basic problem was that we have no house number but a spelled out number is in the house name and the site ordered from had no concept of an address without a number. I realised they'd attempted to deliver to a numbered house down the road.
After much effort I finally got a phone number for DPD that didn't immediately drop through to an automated system that told me the package had not been able to be delivered (the first time I keyed in the package number; all subsequent attempts to any DPD customer disservice number would recognise my number from CLI and not even bother asking). The parcel was then sent out with the corrected label. At the appropriate time courier with an anonymous white van turned up so I went to meet him to ensure he didn't escape. I was handed a package. Not, unfortunately a DPD-shipped package but another one I was expecting. I went back indoors and found the familiar note on the website - not in, left card. I'm sure it was the same white-van man contracting for both firms and, presumably recognising the packaging and not bothering with the label, attempted to deliver to the same wrong house.
Despite the fact that they'd never actually attempted to deliver to the right house DPD insisted I'd had the due number of attempted deliveries and took it to the collection point miles away. I drove over there, picked up the box and took it home. I opened the box and found a right hand mirror.
