Oh goodness!!! What a nightmare for you! NIGHTMARE!!
I would contact CAMPY, not Viner. Once the bike leaves the showroom floor generally warranty on componets transfers to the componet manu.
Campy should cover this. But it'll prolly take some wrangling to get it out of them. Be firm, but be polite. Explain that the lbs is not helping you and that your forced to go direct to them. Really the lbs should be calling campy.
What a horrible lbs you have. I feel sorry for you.
As for the shipping nightmare.... I have to say that I get requests all the time to send things overseas, and they just scream scam.
Sucks that you really are legit, and no reason for the guy to be rude. But the dang fraud and identity theft issues have left us shop owners more than a bit gun shy.
