Still no response from Blizzard but they are offering refunds now: https://www.reddit.com/r/warcraft3/comments/ey4qvr/blizzard_is_offering_automated_instant_refunds_now/
That's good, however this is obviously not being done because they suddenly gained common sense and decency, but to avoid lawsuits.
I wonder if this is all part of a studied protocol to avoid as many refunds as possible. Frustrate the refund process all you can without making it impossible, and just before people are threatening to sue, allow the refunds. How many people just gave up their refund, I wonder...
You know it deserves the GOTY.
