Vodacom charging 75% penalty fees

We recently have planned to emigrate. I went to gateway contact centre to inform them of our plans to emigrate. I have 4 contracts with them. My one number has been with them for almost 10 years. I was told to cancel the contract I needed to pay off the handsets (which I did and the money I paid still to date has not been assigned to pay off the handsets even after it has been accumulated twice) and then my penalty fee for cancelling prematurely was I had to pay 75% of the remaining balance of the contract for each amounting to R14000.00 and receive nothing in return. No data no airtime no sms no nothing. I informed them I seeked out legal advice and was informed they were only allowed to charge UP TO 10% only and this is clearly stated in the CPA. No one can help me, no one actually wants to help me. I have resorted to the NCC for help in this matter. I have stopped the debit orders until this matter can be resolved which is hopefully by the 1 september or I get on a plane and leave. Hoping this will get some sort of attention and assistance sorting the matter out like civilized people.
