Very similar experience. They messaged me informing me of the delivery slot. I was checking on their app the progress of the driver called Jason. 4 hour then 3 hours then 53 minutes on each checks. Last check was 14 minutes and Jason was one street from me i came out. Suddenly to receive a message saying Delivery attempted nobody was in to sign the parcel! I was standing outside with my neighbour! Tried to call them through the app but it was like trying to drawn a fish. After 45 waiting I gave up, Amazon made me even madder by confirming they lie! And offered a refund for something that was a present, I wasted a day waiting for and travelling tonight. Absolute disgrace ! I have now deleted their app
