I am elderly, vulnerable and self isolating during the COVID pandemic. I accepted delivery of my package by speaking through the other side of my front door. I asked the driver to simply leave it just outside the front door so I could bring it in when he left. He kept on insisting that I open the door so he could hand it to me personally. This is potentially of great risk to my health as I am vulnerable if I catch the virus. I had already accepted delivery. All other delivery drivers have been content to leave packages outside once I have asked them to, but not the UK Mail driver, who arrived in a white van with a DHL logo on it. He then complained to my neighbour that I have a problem by not opening the door to accept him passing the package to me. He should be aware of current COVID delivery rules for vulnerable customers and accept a customers simple and reasonable request to leave a package just the other side of the door so they can bring it when he's gone. An awful experience from a simple delivery.
