Re: Vodafone
Vodafone has high street shops. What happens if you walk into one with a customer service issue (as in "it doesn't work"?) That's a genuine question: I've never had need of their customer service.
I had always thought this was an ultimate bottom-line solution if I needed it: O2 and EE staff in shops have always been helpful when asked. Then I tried it with Virgin Media when my cable broadband had failed, and found customer service inspired by Kafka.
