I checked their website and - having inputted the relevant number - was informed that my "parcel is on a van and is dur for delivery" at a time that elapsed around four hours ago.
Now, needless to say, of course, I fully understand that it is the Yuletide season, and that it is exceptionally busy, and, to be perfectly candid, I am in no particular hurry - for, I would be happy to receive (and welcome) the sausages tomorrow or the following day, or the day following that.
But, if I receive a message informing me to expect delivery of a parcel within a specific timeframe of an hour, then, - as I will have adjusted my daily activities accordingly - I tend to expect that that parcel will arrive within this stated window.
I will say that I have noticed (ever since the advent of Covid) that DPD's undertsanding of what constitutes time has become increasingly elastic.
