I feel bad for the OP. For what it's worth, even if there was local Kobo presence, Kobo's customer support is there mainly to keep repeating that screen issues are the customer's fault and not covered under warranty.
I respectfully disagree with the presumption that all readers with larger screens are as fragile -- I have had four 9.7" Kindles and an 8" iRex Iliad and have never had the screen issues I have had with Kobo. It's more to do with shoddy engineering/manufacturing and failure by Kobo to address the issues.
BTW, comments like "I never leave mine in the car" are unhelpful at best, with respect to a $200 reader made in 2015. I have taken my Kindle DXGs on a hike to almost 7000m, as well as to the tropics and the Equator, and never had the issues I've had with the Aura HDs (three out of four with screen problems).
Here is that other thread:
Bad experience with Aura HD

Kobo is the worst....
