Awful Service

My "Hisense TV set screen went black on Sunday morning, so on Monday I contacted the store that I purchased my TV set from, I was told the lady from Hisense was off sick and she would be back by Wednesday alternately I can contact Hisense directly which I did. A call was logged and the TV was eventually picked up on Thursday morning I was told it will be ready in 3 working days, no further information was given to me, I started calling Hisense from Monday morning to find out what the status of my TV was but none of the agents were able to assist, I was told every time that I had to speak to the technical dept and they were putting me through but I was never transferred since every call was cut-off, I spoke to around 8 or so agents with no help from any of them, at around 4 or so i got to speak to Jurgen who said he cannot get hold of the technical team but he will keep trying I am still waiting for his call. On Tuesday morning I started call again and once again every call that was being "forwarded" to the technical dept was cut off. I eventually got to speak to Veronica the person that logged my initial complaint regarding my TV that was not working and she kept me on the phone for a while when she eventually got back to me she said it would be delivered today which is the following Tuesday, at around 3:30pm I called again I managed to get hold of Veronica again this time I was cut off again, so I called again, and was transferred to Veronica who apologised because I would not be getting my TV today since the driver did not have the TV when she spoke to him earlier it was still with the technicians but he left to do his deliveries. She said she escalated the problem to Dineo who also apologises but says they will deliver tomorrow morning I was extremely upset by this time so Veronica said would you like to speak to Dineo I said I don't really care who I speak to I would just like to have my TV back she said please hold I will put you through to Dineo, i held on for 10 minutes and once again the call was dropped. I don't know whether I will receive my TV back tomorrow, but I don't believe I can trust anyone that works at Hisense an email was sent to the service dept as well as to Management or supervisors none of them have bothered to contact me so much so for Service be very careful before buying any Hisense product you never know when you might need a service and whether or not you can believe anything they say
