Misleading Information

This company called me to offer their Explorer Decoder and they told me I will no longer pay the initial DSTV amount I used to pay. They told me I will only pay R136 a month, so took the offer and to my surprise DSTV requested that I pay R496 monthly premium and after a couple of months OnAir TV called me to demand the R136 payment. I've asked the consultant on several occasions that I will only pay R136 DSTV premiums and she said YES. I told them if they are disputing that, then I need a recording of that sales pitch. Furthermore, they claim that I agreed for my monthly premiums to debit every 15th of the month. I never agreed to that, I get paid every 27th of the month, so why would I agree on date that I will have no money. If they don't resolve this I will expose them, this is just the first step. They misled into thinking that I'm signing up for a bargain, only to find out I'm being ripped of.
