Bad bad bad service again from Vodacom

I currently have an active contract with Vodacom and had the previous one which I took in 2018 October. In September 2020 I called their cancelation department to ask if they can cancel and close the contract since I will not want to upgrade or take up a new one. The contract I wanted to cancel was for the 2 Huawei P8 Lite 2019 phones which was linked to 2 Vodacom numbers where one of the numbers a sin card was sent with the phones. The cancelation was done on time and was canceled successfully however this month when I received monthly statement I was shocked to discover that I was charged airtime for the contract that was "supposed" to be canceled.I was also charged the insurance which I was told it will be canceled due to the phones not being on contract. I contacted Vodacom and asked why did this happen as I remember canceling the contracts on time. I was told there will be a turnaround time of 7 working days to request a recording of what happened and I will be informed of the outcome. My concern is their turnaround time is to get a recording not to sort out this mess because I am not happy with this. I will be happy if I can only pay the current contract which is the Sim only contract. If it's not possible for them to sort this out before my pay date which is the 25th they should cancel all my contracts and I will go to another service provider.

I am so not happy with Vodacom.
