Benq — Benq 4k monitor

There are couple of dead pixels which have appeared on the LCD, applied for RMA and the Benq technician called and asked me to send a video of the dead pixel. Sent him the video and he says it is dust, what a joke. I told him I can clearly see it's not dust but dead pixel but he kept on insisting that it is dust. Then after he said even if it's dead pixels RMA is not possible as Benq's RMA policy for dead pixel on lcd monitor is only for 90 days which is again bigger joke. Why is Benq even making monitors when they themselves aren't sure that their lcd panels will not last longer than 90 days. This 90 days dead pixel on lcd policy from Benq is just to scam and loot the customers and deny the RMA. Guys never ever purchase any Benq product, their technicians have very high ego's and talk to the customers rudely, his name is Madan Kumar and the number from which he called is [protected]. I told the technician that I will make a video about all this fuss and upload on youtube and the technician is like ok go ahead and do it. This was absolutely most unpleasant experience. Benq is a company which always finds an excuse to deny RMA and they trained their technicians to give any stupid/silly reasons to the customers to deny the RMA.
