DSTV is a *****

I had to pay DSTV twice for the bill of November I won a free Premium upgrade in the festive joy competition when I checked on the app I needed to pay R170 so I made an EFT according to the person I was charting to on messenger but when I checked on the 28th December 2021 I was again debited an amount R675.67 can you please explain why I had to pay you twice? You guys are of full nonsense.
