Got the 'Tried to deliver' card but they didn't ring or knock, just heard the card come through and thought it was normal post. By the time I got to the door he'd gone.
Royal mail in my old house were useless, I remember arranging a delivery for a day off I had, stayed in all day. Got up to make a tea and on my way to the kitchen I saw the red "sorry we missed you" slip on the floor! Was not impressed
