STAY AWAY FROM ONAIR TV

I would like to make OnAir aware that their consultants gave my parent wrong information by telling them they will not pay any extra besides the subscription payment. Now on Air said they need to listen to the recording to confirm that indeed she was not informed. This was supposed to take 7days it's now 14 days later,I had to call them and they still have no feedback. How can Multi Choice allows to be associated with a brand of this nature that lies to clients and not get back to them. I need SOMEONE to contact ASAP! And sort this mess out
