If you would ever want an example of appalling customer service have a look at the attached document which records the correspondence of a lost parcel delivery between New Zealand and UK,
The parcel was a 30th Birthday present to my daughter Jessie. It was sent by tracked courier with a six day guaranteed delivery time.
The parcel never arrived.
Over a month however Jessie and I dealt with ten known people and an unknown number of others.
The conversations cover 21 pages of text and represent, I suspect, 40 hours of time.
