Evri always used to leave parcels over my back gate. At Christmas one delivery was wrapped in paper and left out in the rain, contents ruined.
I complained to the retailer and received a replacement.
I assume they must have complained to Evri because since then they don't deliver anything. Everything I have ordered has been returned "unable to deliver". Even when I've been in when they apparently tried, they don't knock.
If I've got a choice I've stopped ordering from places that use Evri, but often you don't know who they'll use when you order.
