Appalling Service

It is impossible to engage with Vodacom. I am trying to cancel a data contract I never use. Called all the numbers, followed the prompts. NOTHING. Tried to engage with the Chatbot but it sends an SMS OTP and I do not receive SMS on this device so I cannot proceed. Emailed the Customer service centre who said I should contact the Chatbot. Your service is appalling. How does one EVER cancel a contract. I am just going to cancel the debit order. Don't even think of trying legal proceedings against me. I have tried every way possible to cancel and Vodacom simply does not allow it. Will NEVER recommend your service. So glad I switched my phone contract to MTN hears ago.
