Bad bad after service

I bought a Hisense 65\TV from Hi fi corp on 2015.04.24.<br> Arter about 3 months the TV started to give me problems. <br> It started to go on and off by its self. <br> I phoned Hi fi corp on 2015.10.20 and spoke to Lunga Siphamla .<br> They send technicians to collect my TV for repairs. <br> When I got my TV back the fault on the TV still remains the same. <br> I phoned them a second time and spoke to Emmanuel Mathibe and they send a technician to my residence. <br> He repaired my TV by replacing the mother board. <br> After repair the TV had problems with the picture a.<br> I phoned Emmanuel Mathibe again and he said that he is sending a technicians to my residence again. <br> When they arrived they said that there is nothing that they can do and that they are gonna send some one to update the software. <br> Until no nothing happened for repairs towards my TV. <br> This is the worst services ever.
