What the Hell I Did. [Update]

Thanks for the contributions everybody - here is an update.

I took the cranks back today, armed with a printout of the ebay auction, and chatted with the girl on the counter about it. To their credit they were receptive and didn't try to browbeat me or use the "i know more about bikes than you" card.

I showed her the ebay auction, and she also checked ebay to see if she could find any confirmation of the price (£100). I didn't appreciate it when she pulled up an image of stronglight cranks with a similar set up (adaptor ring rather than built in spiders), but ones that were quite clearly different, trying to claim they were the same.

She also said that the £100 price tag was due to the ebay auction ones being 165 rather than 170 (the only way they were different from the cranks I have), and therefore track specific. Is this a reasonable argument? I could understand it, but I am not a stronglight expert. I think the price was more down to them being sold by hilary stone to americans.

By the way, I am not looking for £100, because I know I'm not going to get it based on an ebay auction and I tried my best to make this clear. ...Er, do you think i'm shooting myself in the foot slightly?

Essentially after a lot of deliberating on her part, she agreed to give me a replacement bottom bracket (because I didn't get the one they removed from the frame back [b]at all, something which I may have failed to mention), but she couldn't do anything about it because Yan (is that his name?) and the others are all in Mexico till next week. She gave me a carbon copy of a piece of paper detailing the cranks and what happening to them and told me she'd call back once they were back from their trip.
