Wasn't sure where to put this, So feel free to move!

Anyway bought a set of rear lights for my Sierra on eBay advertised as a new pair.

-Turned up and 1 is cracked (About 1" long at the top),
-There not a matching pair. (Different brands)
-I tried to fit the 'Good' one and the fit is awful, There's 6 studs on the light to slide into the car and then tighten the nut on the inside. And it won't line without filling the holes on the car. (Which I don't want to do as the original ones sit perfectly!)

Now before I contact the seller (UK based)

Who's responsible for postage I paid from UK to Irl and from Irl back to the UK?
