Its not just the website, if you ring different areas of Vm you'll get different prices for the same thing (e.g ordinary CS and retentions). With all these loyalty discounts, inflated standard prices, introductory offers, goodwill payments etc etc, they have utterly confused themselves as well as customers. However you can use this to your advantage i.e ring them all, on different days with different people and take the best price !
