Vodacom in breach of our contract

<p>Vodacom after numerous phone calls and counless hours of being battered from left to right here is my situation again... Vodacom took over/migrated my contract which I initially held with Autopage after and then I upgraded in June without a handset but they kept on charging me for a handset which is ********** the contract lapsed in September and I am still being charged for a hanset. Spoke to Custmer care, Upgrade Department, Account Department and Technical Department promising that is resolved just to wake up to the same nightmare each month!! What do I do now?</p>
