DStv (Multichoice)

I struggle to get my refund from Multichoice. I've cancelled my subscription wef 1 Jun 2022. On 1 Aug 2022, Multichoice deducted Jul and Aug subscriptions. According to them, my account was still active for Jul. My question then, why did they not deducted the Jul subscription as with previous months? Clearly they do not have an idea what they are doing. I sent an email to Simlindile Khuzwayo at Multichoice three times already (2 & 3 Aug) with all the proof that the subscription was cancelled on the MyDstv portal (this was done on 23 May 2022). They even refunded me the Jun 2022 subscription. Surely this is not "rocket science" to finalize this matter asap. All that I want from Multichoice is my FULL refund and CONFIRMATION that my cancellation subscription is captured on their system. Is this so difficult?????
