New Xbox 360 controller won't turn on with official charge pack but will with batteries?

Thanks everyone for the help I filed a dispute and sent several messages back and forth they kept claiming it was new and a genuine product (and how could we do business and have high rep if we lied?). Finally I sent them all the pictures I had took and all the google info I found and asked them how they could claim it was a legit controller when all this stuff was different?

They finally admitted it was "original" made by a third party though, even though it was advertised (and upon messaging before buying they claimed it) as a genuine microsoft product.

tl;dr - third party knockoff, probably why the charge packs don't work. use the pictures above of the hologram (and other details) as a guide.
