Dstv doesn't want to refund me

I'm very dissapoint in the service that I received from DSTV, I request a refund on the 2nd of February 2024. Until todate I haven't received the refund. The Was a transaction that was made mistakenly on their account of R1700 and I want my money back. They request my details to process the refund they said I must wait 7-14 days for the money to reflect Back to my account. No refund has been made. I Called again and they request my details again and still no refund was processed. I am frastrated and tired, I want my money back, now i have been told that the was an incorrect amount. Who's fault is that and why they keep promising me a refund and not process it. They are ****mers and they keep on deducting on the money they owe on a monthly cover without communicating to me, I keep on calling them every thim since February. We are in April now. Will I even get my refund of the outstanding money of R1200. Is this how they treat people. I want this matter resolved immediately
