Calls worth missing

One of my correspondents made an appointment to get his eyes tested, which involved a wait of over a fortnight but he was put on a cancellation list with a promise of a phone call if a suitable appointment came up.
    He’d barely got back home before the phone range. With a recorded voice doing one of those ‘bank security department’ and ‘charges to your card’ scams.
    Half an hour later, it was a young Indian lady claiming to be from BT and wanting to chat about his internet, even though he doesn’t have BT’s service.
    Is living in an age of ready communications really that much of an advantage?
