After our move the Tv (Q90) stopped working. We contacted Samsung and made an appointment for a technician to come and check it. The cost would be $60 for the visit. The day before the appointment was cancelled for no reason with an email. After several calls with Samsung, they informed me they work with authorized repair services and I should call them directly to make an appointment which I did. Only the day before I got the same cancellation email. Mu issue was escalated by Samsung and I managed to speak with a supervisor who told me that Samsung cannot do anything about the cancellations, other than reporting the issue to the authorized service. So basically one buys a Samsung product but deals with a third party when there is an issue under warranty or not. This is when I gave up. No more Samsung products!
