Misleading agents

I was called to ask whether I wanted a new pvr decoder. I was informed by the agent that the HD decoder was an old one. I specifically asked who is going to pay for an installer to come out to install the new pvr and I was informed 3 or more times on this same call, that the pvr would be a plug and play. Well, when the decoder came guess what I had to get an installer for it which cost me R1400.00. After calling onairtv I was informed it would take 7 working days for them to listen to the tapes to see what transpired. After 9 working days I called back only to find out they still did not listen to the tapes. After nearly 27 working days I got a call to say that their agent did advise me that it was plug and play now I had to wait 21 working days for my money to be refunded. I am still waiting on a refund since 26/07/2022
