Onair tv ***** sales

Misleading marketing from onair tv. I wad contacted by a sales agent, telling me that my decoder is outdated and i will need to up grade to the new explorer, the good thing about this upgrade to a 24 months contract that i will pay a discounted subscription to dstv of R320 for 24 months.month end came i i paid the R320 subscription. 3 days later my dstv was disconnected, so i called dstv and told them that my dstv paid though debit order. They told they have not received any payment. So i explained my story to them about the on air tv sale person. Dstv told me that they have no dealings with onair regarding dstv subscription discounts, and i owe them R420 to reconnect my package. So i called onair explained to customers service about the sale agreement, so they told me that they will listen to voice records, in 72hrs they will call me back, been 2weeks heard nothing from onair. So i cancel my debit order.. On Air tv sales reps are misleading the people to make a sale. I want on air management to contact me regarding this matter. ***** sales.
