Vodafone must be stupid...
I've been a loyal vf customer for 18 years. In that 18 years they've probably had £9000 out of me in charges...so take off 5 new phones over that time, probably £7000 net.
I don't use the phone as much as when I was working, so last June I went onto a basic sim only package, 300 mins, 300 texts, 250mb data....more than enough till last month.
When my wife went into hospital, and I used the phone a lot more, basically 100 odd extra minutes than were on my plan
As soon as I realised I changed the price plan to 600 mins...an extra £3 a month inc vat
