Theres no law saying you get your money back.
SOE shutdown 6 of their games to better use the server for games such as Planetside. Nobody got anything from it however, its just business.
Also, gamespy shutdown months ago, with their severs sold off years ago. Almost all of their game servers have been migrated elsewhere, Borderlands for example still runs.
Gamespy shutdown the BF2MC servers years ago, but nobody complained, since BF3 was out, after BC1 and BC2.
