Onair TV is a ****

I'm beginning to think Onair TV is a ****ming business. When I was going about my business of the day, I received a call from onair agent was quite persuasive in convincing me that I had to upgrade my decoder so I could stream many different channels, including Netflix. She asked why I was denying, and I said that it was because I didn't have a smart TV. She rep**** that because decoder from onair include a feature that would transform my TV into a smart TV, I then consented to sign up. She stated all I would have to do is remove the old decoder and install in the new one. We installed the new decoder as soon as it was delivered, but it was ineffective. After I informed Onair TV of the problem, an agent there advised me to contact Multichoice. When I called Multichoice, they questioned whether I had bought the decoder from them. When I rep**** that I had obtained the decoder from Onair TV, they advised me to contact them directly. I then got in touch with the on-air TV once more, and I've been waiting for their help for weeks. I want onair TV to come collect their decoder right away; I don't want anything to do with this Onair TV.
