Vodacom cancellation department is terrible!

I called Vodacom cancellation department to cancel my contract as I served more than 24 months. I was taken from pillar to post regarding my cancellation. First they verify me as their client on the system using my ID, then when they must cancel my contract they ask for my passport. They are trying every trick in the book not to cancel my contract while they debit me every month. Now I'm told I must go to the branch with my ID and passport. Which technology company tells people to go to the branch during the pandemic. I spent 34 minutes on the line with Bongani and still I'm not helped. My Cellular number: ***.
