Vodacom ignoring cancellation request – no help from TOB

I have sent multiple emails to *** to cancel one of my contract numbers (082 *** ***x) while retaining another line on the same account. I received no response except automated messages telling me to use TOBi. TOBi has no cancellation option and no way to speak to an agent. This runaround violates my rights under the Consumer Protection Act, which requires service providers to accept 20 business days’ written notice for cancellations. I have now sent follow-up reminders and even attempted WhatsApp escalation. If this is not resolved, I will escalate further to ICASA and share my experience widely. I require written confirmation of my cancellation immediately, along with any final billing information.
