Vodacom is refusing to cancel my contract

I have been trying to cancel my contract since November, and they keep moving my cancellation date. I was first told that my contract would be cancelled on the 30th of November. The 30th came and my contract was still active. On the 5th of December I called to ask why my contact is still active. They told me that it was a system issue and that they would do an immediate can cancellation. A week passed and the contract was still active. When I called, I was told that escalations take 15 business days. I waited for the 15 business days, and my contract was still not terminated. Today I received an sms saying that my contract will be cancelled on the 31st of January. It is now starting to feel like a **** and that my contract will never be cancelled. I’ve been having the worst customer experience! I’m very disappointed 😡
