Unable to cancel contract that is coming to an end

I have a contract on my account that is ending on 28th June 2026. To comply with the 30 day notice have since the 27th May 2026 attempted on 4 separate occasions to have the contract cancelled on the end date without success. Each time the consultant says the same thing. "They will escalate the matter to their manager and I will receive an SMS and email confirming the cancellation."

To date have not received any response or notification of the cancellation. A google search says Vodacom no longer has a complaint email address
