MultiChoice, I decided to change my package without my consent and now make it impossible for me to correct it, I paid for two months in advance but they decided to upgrade me and allocate money as they please. Their DSTV Stream app not working properly only show 5 channels for the whole of February and currently, even when I paid for the stream separately. Their whatsapp not working, only sells insurance, phone not answer the whole of yesterday.
