Disgusting!!

I ordered a few items online (THE FIX) one of them being white pants. Everything seemed to be in order until I was trying everything on to see if they fit well. I discovered that the white pants were dirty inside, particularly the crotch area! It is literally BROWN! Like a skid mark… the pants also reek of perfume. I’m disgusted. Clearly the pants have been worn before. I don’t even know what to do.
