Useless DStv

I recently took up a DStv pricelock package and was told via recorded conversation that my installment would be R618 monthly I had to pay a pro-rata rate of R440 which was fine. Now my monthly premiums have gone up to R648 and no one can tell me where the additional R30 come from. I have been calling for 3 weeks and keep getting told the someone is going to call me back, till now i have not received any feedback. Three weeks ago, i called and spoke to a consultant who mentioned that he was escalating my account as we were both in agreement that there is an additional charge which he cannot account for. A week later i called back, only to find out that he had done nothing about it. Last Thursday, i called again and spoke to a "supposedly," manger named Chanel Vivier. She also agreed that there is an additional charge. I then requested a copy of the voice recording and was told it takes 24 to 48 hours to obtain this. The reference for that call was ***-I49. Till now, i have still not heard anything. I once again called today. I spoke to another consultant by the name of Sibulele Siwsa. She advised that a manager was going to call me back and as usual, they never do. I am so sick of running around trying to sort out their mess up. I understand that it is only R30, the point is that if this is done to over 16 million customers, you do the math. I will also be taking this to the local newspaper as this is false advertising.
