PATHETIC SERVICE

I bought 2 televisions from game Brits recently, 1 Telefunken 55" smart TV for R4999, and a JVC 55" smart tv for R5999. The Telefunken is still in its box, I am waiting to move before I have space for it, I used the JVC after 4 days, I noticed that it has got a dead pixel, I went back, traded it for another JVC, after 8 days, the Netflix stopped working, I thought JVC's are poor quality televisions, so I took it back and traded it for another 55" telefunken, while I was there, I bought a home theatre system. Now the Netflix and Youtube apps are giving problems on the Telefunken, I got this TV 5 days ago, I phoned them to tell them, I'll just bring this TV back and buy a Samsung 55" and then I'll have piece of mind when it comes to quality, they said; "If I have used the tv, they will send it to the manufacturers.... ALL OF A SUDDEN?????? Now that is their policy all of a sudden. The home theatre system is also giving problems, I noticed the problem just now, I haven't infromed them about it because it is clear what they are going to tell me, they sell BAD QUALITY goods and don't go the extra mile to make things right.
