Ripping people off/poor customer service

So 14 months ago I recieved a call from Onair TV and I was promised a DSTV explora and It was not explained to me that for catch up, I needed to pay an extra R95. I remember asking the consultant and she said it is included. Because I was disputing the fact that, I can't pay R139 over 24 months for a decoder plus installation which is over R3 300. I was told I needed to install a new connection, mind you, I already had a dish installed with extra view. I've been waiting for them to send me an updated statement, to date, I haven't received any.
