Onair is a ****

My mother was told she was signing up for wifi and a decoder that she would be paying only R250 a month now when we call we are told there's value added products added she never requested for, we called the call center several times to cancel any services we have with them but they keep putting the phone down on us. So this tells me that these people are ****mers who deceive customers into signing up for things they don't want, I want any service or subscription canceled with onair .
