Yes true, I suppose those that were sold 500mb may not be able to argue the 10% rule as there was always the chance that Voda would enforce the soft FUP.

However I still believe that people have the right to cancel on the basis that Vodafone (in my case at least) have not notified it's customers of the changes to their contract with regard to the increase in data roaming charges. AFAIK these charges are now in place and I wasn't given any notice of this whatsoever! I think their contract states that they will give 14 or 30 days notice or whatever, which they haven't done and is therefore a breach of contract.

Again some people say that roaming charges do not form a part of the contract, but these charges are referenced in the contract and therefore regardless of whether the specific prices are published in the contract, they are still a part of it!

Just because Vodafone choose not to publish their charges in their contract doesn't mean they have free reign to charge people what they want for whatever service they want. My specific monthly cost for my tariff isn't shown on the contract, but I'm pretty certain that they couldn't suddenly decide to charge me double for the same service! I know this isn't the same as the enforcement of the FUP charges, but the principal is exactly the same in that the specific costs are not stated in the contract, they are only referred to in a general manner, but they still form part of the contract.

I hope this makes sense... I know what I mean!
