I have a dstv account n I am paying for 4 other family members. My issue is my TV is not working and DSTV cant freeze my account because of their terms and conditions. I want to know why must I pay for something I am not using. This conditions is put there to disadvantage its customers n benefit multichoice. I wanna know the person who put the term there why must I pay for something I am not using. I spoke with Zintle Mbongwe a team leader at your call centre she did not even know ombudsman or their number. I just wanna know why must I pay for something I am not using. if dstv doesn’t want to freeze my account because of a term that disadvantage me as a client. I will cancel all the the DSTV account I am payment but I will still take DSTV to court and get the explanation why should I pay for something I am not using.
