Vodacom disgraceful and lacking

I'm absolutely disgusted, frustrated and angry with vodacom. I did not upgrade my 2x data contracts for approximately a year and so it became a month to month contract. I Cancelled the contract in October 2020, but up until today, it's still not cancelled and each month I'm being charged!!! I've called Vodacom on numerous occasions. Should they look at the report/history, it will be a book long report to read. I've sent them the email proof and call dates, but they say it's being esculated and every time to explain it over and over. What utter nonsense! The cancelation dept blames the accounts dept and accounts blames the cancelation dept, but I'm the client that sits with problem. Every month I call with the promise it will be sorted and cancelled. Every month I get a statement with charges occurred and when I call, nothing was done. I'm getting a bad status on my credit report due to this, just because they can't do their job, I'm the one being discredited!!! How will Vodacom fix this!!! I'm tired of all this, too take 6 months trying to just credit the debits raised on the account incorrectly and then to cancel. What is so difficult!!!!! I'm done with Vodacom and to think that I've been with them for more than 20 years. I know that a message will come up stating that a consultant will contact me, but that's not true. I'm going to take this matter further.
