According to the latest reports, Blizzard has bowed down to pressures from the Korean government and revealed its new refund scheme for the local gamers. This action came after the Blizzard Korea’s offices were raided by the authorities (link) when hundreds of gamers were denied a refund due to unstable server connections and services.
As of now, every gamer who registered before 21st June 2012 and is below level 40 will be entitle to a refund. Gamers who registered after 21st June 2012 and are not able to reach level 21 in 14 days will be entitled to a full refund as well.
There is also a notice that for all refunded copies, the data will be deleted (characters, gold, items etc). As an extra benefit, Korean gamers for Diablo III will be able to apply for a 30 days pass for Starcraft II starting from 25th June 2012. Game time for Starcraft II is limited from 14th July 2012 till 12th August 2012.
