Just received a leaflet from Vodafone to say that access to their Vodafone Live! service will be charged from June 1st onwards, having been completely free for the past few years I've been with them. Users will be charged up to £1 a day for the first 0.5mb, then the next 14.5mb is free, then it's £2 for each edditional mb. This is a laughable pricing structure (basically £1 for 15mb, but you get charged the £1 when you get to 0.5mb...), and to say I'm pissed off is an understatement

I'll be making the change when my contract ends in July.
One question I do have, are they allowed to just suddenly changed the pricing structure like that, even though I'm in midst of an 18 month contract?
