A thread on the Diablo III forums has a complaint from a user who claims to have been charged $149.99 for an item in the Real-Money Auction House for Diablo III after bidding on an item they say was posted at $0.00. They offer evidence to support this claim as well indications that the bug they encountered is still occurring. On a semi-related note, this thread has the account from a user claiming to have lost a Battle.net balance of $200.00 after changing the region on their account, while this one is from someone who says they called the FBI to report Blizzard for wire fraud, alleging having never received a $49.99 payment for an item they sold. These threads have attracted a lot of attention from users, but so far have received no official "blue" comments from Blizzard. Thanks Joao and Blend Games.
