Refund not being made

I cancelled my DSTV subscription at the end of June 2019. DSTV still debited my credit card.

I have struggled ever since then to receive a refund.

On 17 October I received a call from DSTV that the refund will be processed within 3-5 days and my banking details were confirmed.

To date, I am still to be refunded.

On calling the Multichoice contact centre, they said they can't help me and referred me to the financial centre. The telephone number they supp**** was not valid.
