Dstv stop ****ming us

On the 3rd of May I did an add in to my subscription of Disney plus.... And I couldn't access it.. I than called dstv customer care and I explained to them my challenge, and they said I will not be able to use it I need to pay immediately.. I than asked them to cancel it on their side as I have already activated it on my app..today when I wanna make payment iam being told about outstanding balance of Disney plus. According to my knowledge it was removed the same day I activated it.. So who must pay that amount? For something that I never used.... He'll noooo u ****ming me. Can u kindly get me the proper amount iam supposed to pay which ie R149. This R303 won't be paid by me...
