Trying to cancel a Vodacom account

I would never recommend anyone to take up a contract with Vodacom, it has been 3 months since my contract ended and since July i have been trying to cancel the contract and stop the debit orders. Every month I hear its been canceled and they will refund me, 3 references later and still nothing. Today I spoke to Stembele Ngubane at cancellations, he advised that he will listen to the recordings and then make sure the contract is canceled and request a refund, but thats what I was promised wen i called i initiallly called in July and again in August. It is difficult times you cant just be taking money out from ppls accounts. Its very unfair to your customers
