Hmmm....I got a similar email from the directors office, however mine said "I appreciate you were told that you had a price plan with unlimited data allowance, what we're doing is clarifying exactly what we mean by unlimited data allowance (500 Mb)".

Sent a "nice" response to this with the Oxford English Dictionaries definition of Unlimited too.

Still insisting I terminate my contract with no penalty and copied in the CEO's again as well.

They will love me
