Lackluster service from TCL. Think twice before buying this brand!

Although TCL has amazing TVs, their technician and customer service is pathetic. My TCL tv (55 inch QLED), is not even 8 months old, and I have an issue with the power board. Not only that, I had to wait all day for the technician to come to my place, at 19:30 that evening, only for him to say that because the tv is older than 6 months, they cannot offer any form of refund, and they have to replace the power board. I have been waiting now for over 2 weeks to get this issue sorted. Surely a number one rated TV brand shouldn't give a lackluster service like this. It's not like the tv was cheap. Also what's to say that the tv will even work when the power board is replaced. If it doesn't work, then how much longer am I expected to wait. Come on TCL. This is very bad service for a brand and product that should be top notch
