There is no customer support and you wait 1.5-2 months once your TV is broken under warranty.

I bought a 75' TV 5 March 2021, it is malfunctioning, two lines one screen and auto shuts down every few minutes. Reported the case on Samsung websites 22 September 2021, today 18 October, I am still waiting. Technician was at my home 30 September to access it and saying panel need to be replaced, got a call 6 October saying no stock of panel, Samsung will replace my TV and no further update, I contact them back they say they will check and let me know which they never do, got hold of their live support now, they saying the case is waiting for final approval on replacement, and it takes 7-14 working days!!! and off course after they approve it, will still take some time to get the actual replacement unit, so if you buy a Samsung TV and it breaks down, you might sit for 1.5-2 months without TV and it is their product fault not mine. And they call themselves a world leading brand. By the way, their support system is useless as anything you can imagine. You can not reply to email they send to you, every time you have to go back to their website write a new contact form and given a new ref number when they write to you. We in 2021, company like Samsung when you report something you can not follow up with the matter via same email, but new case every time and guess what, even you quote the previous ref number, they still have no idea what you talking about and ask you to so same thing over again and you can not even reply and tell them to read what you said previously.....
