We've had a new courier recently who is brilliant. My parcels are always one time, his delivery estimates are spot on, my parcels arrive in perfect condition and he is really friendly.
For some reason, every time he is away I am waiting several days longer than the estimate for my parcels and they are quite often left in someone else's back garden so I have to go hunting for them!
I was due a parcel last Thursday which didn't arrive until the following Tuesday and now I have one parcel that was due yesterday (next day delivery paid for!) and one due today (paid extra again!) and neither are even showing as having left their warehouse.
The week before last I finally received another parcel 3 days late after the courier chucked it in a garden in another street and the recipient found it behind his garden chairs days later!
A couple of months ago I had a Next clothing order which was left on my doorstep late in the evening by a guy who walked up with a cigarette hanging out of his mouth!
When I've called the contact number, I have to leave an answerphone message and someone emails me several days later.
This isn't a free service, you are being paid to deliver parcels.
