**** service and day light *******

I subscribed for the R80 on top of the R469 monthly premium and I was supposed to pay R549 on the 10th of this month. My dad made a mistake and went to pay R469 at the shops and we have a debit order for the 10th. But to his surprise when he got to the till point he was told that he owes R800. R800 for what, how did R549 changed to R800. Our agreement with the sales person was that we will pay 549 and as advertised on TV. We are being ****** and now we supposed to pay almost R300 more and I don't know for what. Is it because people are canceling these premium now they want to cover those monies by robbing us. I am furious this is disgusting
