This courier thing has gotten stupid. I know accidents can and do happen, so understand the requirement for packing items properly, however it really shouldn’t be such a lottery as to whether or not your parcel disappears into a black hole or not.
It seems that there’s actually no reliable courier, one person will recommend one, then the next moment you’ll hear a load of horror stories about them.
Regarding disappearing parcels, a parcel can’t just disappear. They surely have cctv throughout the depots, don’t they have it in the vans too?
