False information from the agent

The OnAir TV agent gave me false information. She told me that the R259 includes the monthly dstv subscription which turns out to be lies. I received the explora ultra decoder in July and when I was activating it the agent from dstv told me that I have to pay for the subscription separately. I sent them a message on Facebook asking them to cancel the contract and collect their decoder. The agent told me that the cancelation period is 7 days and since it's after 7 days they can't cancel it. I'm soo disappointed in OnAir TV. I wish I read the reviews before taking their decoder.

I want to cancel the contract with them
