How did the top look in the photo in the auction (did you overlook the flaw)? Is this a flaw that would be apparent to anyone - including someone not familiar with Oilily? I don't know that I agree that you should get your money back; buying on eBay isn't like buying at your favorite retailer where you can return for most any reason. I just feel like this is a grey area when it comes to an eBay purchase.
Have you tried washing it and drying it flat to reshape it?
