Control cancelation

I have been trying to cancel my home internet since last year November and every time I call I hear it's in the process of being canceled. Last week Monday I called and spoke to Makhanda who is the manager at the cancelation department who promised to get my query resolved within 72hrs but I'm still waiting and when I try calling today vodacom tells me my number has been blocked because of the number of times that I called in looking for assistance . Vodacom is a **** and they are reaping us of, imagine trying to cancel a contract for four months and still nothing happens. This company has hired *********** mangers and the company itself is just money making business at the cost of its clients
