Atrocious. Received a blank card on Saturday, no info apart from the reference number. Booked redelivery for today and left note on door stating that I was in the back of the house and to either knocked loudly or short through the gate. Found a comment that they'd shouted and knocked three times. There's nothing wrong with my hearing. I manage to hear every called yesterday above drills and hammering, and today was sat in complete silence. Needs to go back to school - the first person I've ever encountered incapable of spelling the word 'didn't '.
