are you sure they were "Cyberstork"s ?
and if yes, that is the first trouble I have ever heard....
also, Cyberstorks are flat to begin with so if yours were bent its because A, they weren't Cyberstork, or B, you didnt put them on properly.
Another point, Cyberstork doesnt retail outside Japan, unless its through me... B) so, I have to question this posts legitmacy... <_<
