Silly Moo
I have had deliveries from Parcelnet, much better than RM, at least I am home from work when they come and I don't have to drag myself down to the RM sorting office, ring a bell and wait whilst someone decides if they are coming to serve me.
That's your courier's choice to deliver then.
If they give up/are on hols, it could be an entirely different ball game.
