Although as a Vodafone PayAsYouGo customer I know to my cost that they are certainly extremely devious and unscrupulous (for instance hiding the fact that their supposed Passport deal of 75p fixed per incoming call in other EU countries does not apply to calls that originate from the country that you are currently on holiday in and always hiding on their website the real cost of 084 and 087 calls and the fact that they are also excluded from the Passport deal) they are not generally speaking administratively incompetent.
