Refunds are ignored

Once again I need to revert to alternative means of communicating with Vodacom as the normal support channels achieve zero results, zero feedback and no acknowledgement of my queries.

I have requested a refund as I had cancelled my account in April this year yet Vodacom continued to bill me for several months there after. This was eventually stopped after I had submitted a complaint via hellopeter.com (https://www.hellopeter.com/vodacom/reviews/please-cancel-my-***-***).

So once again could Vodacom kindly revert on my request for a refund.
