To be fair, I've never had any problems with deliveries from Evri, or even Hermes as they were previously known.
Yodel however have always been a nightmare. I have never forgotten the day the Yodel van pulled up outside my house, driver got out with a parcel, walked past both the room I was in and the front door to get to the window of another room where the fanlight was open, and lobbed the parcel through it. It landed on the quarry tiled floor. Luckly it was well packed and didn't break. They have also put parcels in the wheelie bins.
