I've just received a message off Vodafone telling me i'm

"...nearly at the end of my monthly data allowance of 500mb."

It seems to contradict it's self.

"If you need to use additional data there will be a charge of £5 incVAT per 500mb, however we won't start charging until 1 October 2010."

So if i go over my limit this month or next month, will i be charged?
Or would i only be charged if i go over my 500mb limit in October?

Either way, thats a big change to the T&C's so i think a cancelation might be in order.
