The phone rang.
There was a pause, then a click - this means a call centre with a computerised calling system that puts answered calls through to someone.
"Hallo Sir, I'm calling on behalf of EDF (France Electricity) to ensure that you received your last bill."
I was suspicious. They've never done this before.
"Yes. It came by email as usual."
"Also to ask you if you have considered the benefits of installing photovoltaic panels on your roof."
"Madame, it is clear that you do not work for EDF because if you did then you would know that this is a block of flats and we are tenants, not owner-occupiers."
The phone cut off suddenly.
