Vodacom - Deplorable customer service

After calling 4 times to cancel a contract after the contract period, and the consultant confirming the same, I found out that they cancelled the insurance on the device and not the contract after reviving the bill for the following month. This is purely corporate hooliganism. In fact I was confirmed that my contract was cancelled. Don't feel like continuing with my other contract with them. To make things difficult for customers cancellation options is not there ion their site nor in their app.
