you'll prolly get an official reply from Yellowbeard (he's based in the US IIRC)
but he replies to most/all corsairs threads (unlike ATi's support team....) but he's a top bloke and nice to deal with
but i'm pretty sure that corsair will sort you out...
i think.. that it is bluebeard that deals with the cable side of things.. cos blackbeard is the UK corsair dude and i'm not sure about rebeard, all i know is that he is stateside...
so yellowbeard may pass this onto bluebeard

, i think bluebeards based in sweden aswell.. don't quote me on that tho...
and i don't think that the language of the invoice matters.. aslong as it is an invoice...
edit:
see
HERE
and it looks like bluebeard is german not swedish
all the beards have confused me
