Same here,
i think that it's buyer fault,
if he claims that seller stated that "Package type 478-pin Micro-FCPGA",
what about the picture?
the review posted by TS,
there stated that 479 socket has the two missing pins diagonal from each other
so which one is true? I guess TS should confirm with seller first, did he? no?

Anyway, it's really good that seller wish to refund.
