Bad service by Samsung and technician - ***

Bad service from the Samsung technician, my tv has been in for repairs since the 24th of January 2019, it has not been returned. I first bought the tv (Samsung 43" Smart UHD LED) on the 4th of December 2018 at Makro Alberton, then returned it to the store on the 8th of January 2019 due to malfunction. On the 17th i was called to fetch it as it was back from repairs. On monday the 21st of January the same problem started again, the HDMI output was only functioning after a day or two. I returned the tv to the store on the 24th of January, a technician from Samsung called and told me that the problem is my DSTV, which i find as ridiculous because my old tv works perfectly with the same accused DSTV. To date (03 April 2019), my tv is not back yet. Is this how Samsung treats its customers? Such a bad experience!
