Showmax bill double invoice through dstv account

Hi there am tired of paying for my show max account double I pay from vodacom bill but I still Get charged every month on my dstv bilbeven after canceling it.. It goes through...I didn't really care at first but now I do bacuse every single month I pay a different amount for my dstv... I want all my refunds back credited into my dstv account... Investigate it or talk to show max I don't care just stop adding the showmax invoice on my dstv because I pay via Voda.. But refund me thank you
