I might be out on a limb here, but surely the courier or delivery driver have a duty of care to deliver as addressed or to a recognised location?
After trying and failed to pick up my parcel , when I was home and a poor attempt from the driver to deliver, even despite the firm notifying me when it was due, I was quite aggrieved and complained vigorously to the deliverer concerned, so someone has got a rollicking for it , too bad , they should have got it right first of.
I have done the job myself as Royal mail postie. Done it for years , so I do know what's what, it seems to me couriers are sent out with a van load of parcels and are over pressured to not take items back or attempt redelivery, the depots do not have facilities in to hold packages that not delivered.
The fault is the consumer not recognising the pressure excerted by contractors, on non committed part timers making a bit of pin money on the QT,
It's got so now I ask , who delivers my orders, if I don't trust the deliverer , then I request it's sent by Royal Mail, but even then that's been dumbed down from what it was.
Its time the customers , that's you and I ,demand better service, rather pander to the convience of some oik who really can't be arsed to do what they should do
