24 Month unused Data Cancellation Penalty "REASONABLE"?!?!

I have a 36 month contract with device with Vodacom.

I saw they were apparently increasing contract fees in light of tough economic conditions, which I do not agree with (what about the consumers?).

I requested a cancellation quote and was informed I was to pay effectively the entire remainder of the contract (24+ months of unused data).

I tried to escalate internally, phoning, phoning, twitter, Facebook, but still no solution!!!

I have looked for the CPA / NCR and ombudsman contact information to try get a solution, because Vodacom is NOT reducing the unused data cancellation to a reasonable period (Telkom LTE cancelled a data contract with a 3 month penalty fee. That is reasonable. Vodacom's 24+ months is NOT!!!!)
