Query: Very disappointed with the one I got. Want to exchange!!!

I read the reviews before my purchase and had faith in the quality of B+W products. However, after I got this filter, I was really disappointed.The words "Made In Germany" were skew in printing and partially missing. Cause it would be very inconvenient to exchange, I told myself, "Ok, it might not be that bad." But, when I installed it on my lens, every time I looked down, it looks really awkward and ugly. I want to exchange for another one.
