5 months of trying to cancel a ********** contract

After having my contract **********ly upgraded 5 months ago, I am still trying to cancel the contract. Nobody at Vodacom seems to be able to assist, not Vodacom shop staff and certainly not the call centre agents. After calling every possible number, from customer care (082 135), cancelations (***), creditors and accounts (***), I have still not had my issue resolved. Every department refers me to another. Calle center agents drop your call. Nobody is willing to give you a reference number. I am appalled at the poor customer service I have received, and the lack of responsiveness from Vodacom.
