Cancellation Call Center

Once again no joy out of the Vodacom cancellation call centre. Called on the 21st December 2021 at 13:26 and spoke to a call centre agent for 18min 11 sec to cancel a contract that came to a end on the 22/07/2021, up to date the contract has not been cancelled. Furthermore I had another contract that was coming to a end and the agent told me that he will lower the monthly installment to R79 and give me 5gb of data a month, what a lie I am still paying the original amount of R279 for the past 2 months and the contract has been upgraded to end on the 15/02/2024. I would like vodacom to cancel the contracts with immediate effect. And I will be closing all my contracts with vodacom as I cant trust the service provider anymore. Vodacom cancellation call center is only there to disappoint a person!!!!!
