The game was recently released, but unfortunately, many seemed to be extremely disappointed with it where reviews of the game were mostly less than favorable. This is why it doesn’t come as a surprise to learn that Blizzard is now offering customers automated and instant refunds via its website.
It seems that it does not matter how long players have spent playing the game as these refunds are all automated and are more or less instant. Typically refunds need to be processed and a good reason needs to be provided, but according to the post on Reddit, Blizzard seems to be automatically processing these refunds regardless.
It is unclear why Blizzard is being so “generous”, but as some have speculated, it could be due to concern that the FCC might want to investigate the company as some customers have been spreading some complaint links, and that this is a quicker and quieter way to revolve it before it gets out of hand.
