Misleading OnAir Sale, whatever you do, do not take up their R119 offer!!!!

My dad received a call on 18 December for an offer of 2 explora decoders for R119 each. At the time he assumed that it was the DSTV price lock offer and decided to take up the offer. The guy who sold him the deal did not make make him aware that this offer does not include the DSTV monthly subscriptions. We only found out after the installation and tried to call and cancel within the 48 hours cancellation period. The 48 hours has since passed with unsuccessful attempts trying to call the OnAir call center. Today, when we eventually went managed to call in, the agent on the call said that they cannot cancel and my dad will have to pay the full 24-months subscription. All we want to do is cancel this misleading sale. Every person has a right to cancel, especially if the sale was not done in good faith, I would assume that refusing to allow a customer to cancel a service is ********* and goes against consumer laws. I also fail to understand why DSTV would work with such an *********** third party.
