Vodacom doesn't care at all

Vodacom refusing to resolve their breach of contract and one has made a final decision never to take any vodacom contract. Now exiting the phone contracts after 20 years of being with them for the last 5 years was horror. Never. Their wifi contract am waiting for it to expire as they bullying me with hefty cancellation bill for breaching whilst in their breach they don't care and are willing to abuse their rights.
