Haha, similar thing happened to me with a 50mm f/1.8 (not the same price range, I know).
I bought the lens the night before I bought my 40D, because I was in the city that night so I figured I'd save myself a trip. The next day I opened it to check it out (still didn't have a camera to mount it on at this point), and there was a scratch on the rear element that wouldn't come out by buffing it. Needless to say, I was p****d. I called Rainer's and spoke to someone who told me to bring it in.
I walk in, hand it to the staff member. He walks to the back of the store and hands it to Rainer. He takes a quick glance at it, tells me that I've scratched it, and tells me to get out of the store because he's not replacing it (yes, those words).
Things got a little heated (because I don't like being called a liar). He told me that there's no way that it left his store in that condition, and there's no way Canon would replace it because it's an obvious thing that I'd done. I said that's not my fault, I'd bought a damaged lens from him, and as the retailer, he should be doing what he can to resolve the problem.
He told me to "Get the f**k out of his store, and stop wasting his time with this BS", because I was obviously the one who caused the damage. Blah blah blah, I ended up just leaving it there on the bench.
He called me like 5 hours later, saying that he looked at the lens and it turns out that the "scratch" was just a really bad mark. He had to buff the s**t out of it, but it came out eventually (what kind of "mark" that is I don't know, but it was as clear as day). When I went to pick it up, he told me to never come back to his store, even though I was right!.
Either way, yeah I was disappointed in Canon's QC, because that mark was as clear as day, it was huge. And f**k Rainer, too. I was dumbfounded at his complete lack of diplomacy, customer service skills, and integrity. Telling a repeat customer who has spent nearly $2k in your store to "get the f**k out of here" for bringing back a damaged lens is mind-blowing.
Cant believe the guy is still in business... 



) down the track.
Just ask Ruth. Just remember to take the camera gear with you.
