This is a true story.
I've seen this happen several times. So grateful we don't have to deal with Chorus for fibre in Tauranga...
Day of client's VDSL install:
Chorus Tech calls client and asks: "Is this a VDSL install?"
Client: "Yes"
Chorus tech: "Good thats what the job says... but I don't do VDSL"
New install rescheduled to a date that is days away.
