DPD and I are not friends, lol. Amazon get lost, but they'll ring. Royal Mail sometimes get lost if they're delivering a parcel and don't do the normal post rounds, but they turn up. Evri have managed to find their way on a few occasions (I don't have Evri deliver often). DHL know what they're doing.
DPD? I'm on an unofficial list in the local DPD depot. I probably have been since the sewing machine incident last year. "Sorry we missed you, we couldn't find your address" "Sorry we missed you, you were out" (with a photo of the wrong house). The guy who did the last couple of deliveries has been lovely though, not his fault he works with a bunch of morons.
