Poor service and lack of feedback from On Air DSTV

I was contacted by ON Air DSTv about a month ago. The caller said he was from DStV . I got the impression he was from multichoice. At no time did he mention specifically ON AIR DSTV. He then went on to explain that the current explorer 1 that I have has huge problems and that soon I will experience this as well. He explained the problem to me and I stated I have no such problems. He then went on to say they will guve me an explorer 3 as an update for R180 per month. I asked him if he is from multichoice and he kept saying he is from another call center but from DSTV. At no stage was On Air mentioned. I asked him about the explorer ultra and he said for now they can only provide the 3 as ultra is not yet available. I agreed to the service and they arranged delivery and installation all within a week. I did not get a follow up call or email. 2 weeks later I received a call from an insurance company confirming the installation and they wanted policy number . I was confused as 1 received no emails. It was then I told that it was not DSTV multichoice but ON AIR DSTv that sold me the unit. I was shocked at this first time information. I phoned multichooce who confirmed ON AIR works with them. They then gave me a contact number . I called the switchboard many times.First I dealt with Pretty who said I cannot cancel as the unit has been installed and of I want out I must pay the contract out. After making a fuss about the misrepresenting of sales and requesting the recording as proof I was given a ticket number and told to wait. 2 weeks went bye and then I received a call after I sent reminder emails and made some more calls ..that the recording was viewed and that they were clear in stating to me who they were and what they offered. After challenging them I was Transferred to a guy called Sameshan . This guy was young and ****y. He started shouting about company policy and that it is not allowed to view recordings. He then went to lecture me about my tone of voice and then he promised to look into the matter. After that I received another email stating my ticket was resolved and hence closed.. Its now March and I haven't gotten any feedback . I did not get any voice recordings to listen to. No one senior emailed me back asking me what my concerns were and how to resolve them. I am still waiting. I am still sending emails. I do not recommend supporting ON AIr. They are not honest in their dealings. Lack professionalism and clearly lacking knowledge on how to do deal with complaints.
