Bests & Worsts Reviews from Amazon

I purchased three beige panels, two of them had dirt on them. One of them was ~3/4" longer than the other two and the color didn't match with the other two. I didn't really quite understand why two of them had brown dirt on them about 3x5 inches wide, why one was longer than the other two, and why the color didn't match. They have a very poor return policy. Item must be in original package, NOT OPENED, and not used. How do they expect me not to open the package? Am I suppose to use my psychic power to see if these curtains are defective? I ended up keeping all three of them since I can't return them. I had to wash and spray shout on the two curtains that had dirt on them. They are definitely NOT blackout curtain, maybe room darkening. I will upload some pictures so you can judge it yourself, including "Blackout" curtain quality.
