After an especially horrific experience with ASUS ‘tech support’ trying to get them to RMA a defective motherboard, I too have given up ever buying another one of their products. Support was the worst I’ve ever experienced in my 25+ years of dealing with tech support - and I deal with tech support a LOT in my job.
It got so frustrating that at one point I was literally screaming at them on the phone in front of my customer. Very unprofessional of me, but I’d snapped. Thankfully the customer had been privy to the lunacy I’d experienced onsite with them for over a week trying to get resolution for a problem that after doing my own troubleshooting I unequivocally knew was a defective board, so they understood why that happened. I wrote a letter to ASUS corporate detailing the terrible experience, for all the good it would do…which is none. Shame, really, because overall I know they manufacture some quality products. The level of incompetence on display in their support dept., however has made them dead to me.
