I think dpd are fantastic, never let me down!
The other couriers are mediocre in comparison IMO
Wish apple would ship their orders with dpd
Whilst I agree that their tracking is good when you get the information. And then the time estimation seems to be spot on on the day as well. And the drivers are very courteous. When all goes well it is great. However when it doesn't, and you don't get the number through or you do and the you don't get your slot and then nothing happens. That is where it falls down in my experience.
