“Welcome to BT. If you are calling about sending a monkey to the moon, please press 1…”

Once upon a time, it was perfectly possible to ask British Telecom to do something in return for money. You would ring an 0800 number and someone in India would politely accept the premise that if you paid them, say, £70, they would send an engineer to your home to carry out repairs.

This used to be true of Sky TV as well, before they decided that there was virtually nothing about their £50 a month service they would fix other than by giving you instructions down the phone to make you fix it yourself. ‘But the box has blown up into a million pieces!’ ‘Yes, madam, and we are going to talk you through reassembling it using the simple principles of thermonuclear fusion.’

But that’s another story. Let us stick to the nightmare in question, which was what happened when I rang BT to ask them to move my broadband router.
