Contract Cancellation

If I could give them a 0, I would, I always looked up to Vodacom and wanted a contract, got one and it was great a few months in and then the trouble started, first my premium increased without notification and when I called in, they stated it was due to inflation.

When I called in on 23 Sept 2022 to cancel my contract the agent gave me a different story why my premium increased, but I still requested to. Have my contract cancelled. The agent assured me that it will be cancelled... Since then I made a few follow up calls and to my frustration, every time the contract was not cancelled till today.

Started with a nice experience, but now I do not want to have a contract with Vodacom anymore, because this is unacceptable, I know that they do not want to loose a client, but with this behavior I do not want a contract at all.

I emailed their customer service center and this is day 3,still no reply.

Can someone please advise me how to go about, even by using a 3rd party to get this contract cancelled without having to put my credit profile at ristk for non payment.
