dianapeUnfortunately, this is Asus' standard customer satisfaction policy.
After reading through a couple of posts by you and others in this forum, indeed "Asus is regrettable". I'm never buying ASUS products ever again and won't ever recommend it.
The current Zenfone 5z (similar configuration as my old one) costs 33000 INR approx. in India. If company is quoting 37000 INR for motherboard replacement, it means they are refusing service and don't need customers at all..
