Unhappy customer

I logged a complaint on hello peter against Vodacom. I was contacted by Vodacom on the 3/9/21 and was told they would look into the recording of my conversation with a consultant who said I'd get a refund. On the 11/9/21 I receive smses saying in progress and another saying my request has been attended to. I have not received any feedback after my complaint since then. I don't even know what the outcome was. This is really disappointing. There was no resolution.
