I regularly have to wander around my development to find items which Amazon delivery has randomly abandoned, sometimes contacting a very apologetic but otherwise disinterested customer services agent.Today I had a guaranteed delivery by 1pm. What happened? The driver claimed he couldn't find my home (despite an Amazon delivery at the development every day, and a mailroom and concierge - who takes parcels - at the main door. They called, I complained, they guaranteed delivery today, and yet, nothing has come. I can't get a refund as I need the undelivered items to return them.
