IME - a spectrum of quality depending on what you pay for. DHL and FedEx at= the top (and JohnLewis own people), PostOffice was excellent in my village= - but now reorganised so second rank, ParcelForce poor as their nearest de= livery centre is 50 miles away, and down at the bottom various names that m= ake me groan, or nameless subcontracted white vans.
In a very rural location like mine it tends to nearly always be the same on= e person per company driving the van. So it comes down to that person, and = I'm learning which ones are illiterate (seriously), unable to find a letter= box, have suddenly lost the use of their legs and are unable to leave their= van etc.
Some van drivers organise the back of the van like a filing system and can = instantly find anything. Others wade around in a heap of rapidly-getting-da= maged packages.
Complaints to the individual, or to the company are utterly wasted breath.
I guess there's been a rapid increase in demand with online shopping, lots = of new players competing on price alone - eventually it will settle down wi= th fewer cowboys, as businesses realise their reputation is damaged by cowb= oy delivery services.
