Bad Service from OnAir

I got a decoder from OnAir last week and when I connected it, it didn't work.Took it to multichoice to get it connected and it still didn't work. All the features I was promised on the Explorer Ultra did not work. I then spent 2 hours on the phone again trying to fix it but still nothing.

I reported this to them on Tuesday and requested a cancelation and they are ignoring my request.They still went ahead to Debit my account for their decoder that I reported was not working and they basically just left me to pay for a decoder that is not working.

Basically they sold me a decoder that is not working, and they are refusing to change it.

Really terrible service I got from them and I would like to warn people not to buy from OnAir.
