Pathetic service - Refusal of contract cancellation

Around December 2023 and January 2024 posted a review regarding my contract and the issues I faced with rewards co, the company subcontracted to Vodacom for new contracts and renewals including cancellations.

After numerous emails and phone calls and complaints the company finally cancelled my contract. However as the year went by I received emailed statements from Vodacom for a line which is still active. The contract was initially for a double deal but after querying the statements with Vodacom they now told me I was supposed to cancel both lines which no one explained. The agent was more interested in convincing me to not cancel. I explained to a number of agents to date that I await a response regarding the issue and all I get told is that they are reviewing the call records and will revert to me. To date 2024-07-09 I have not received any feedback from Vodacom regarding the issue even after numerous emails and calls and they still are invoicing me each month.
