I’m not sure what my hassle threshold would be but in this case we’re talking three figures, so I was definitely not letting that one go!
And come to think of it, when I originally ordered the three MOB outfits, I received, separately, two outfits and a kitchen rug! Oddly, there wasn’t a box to check on the return form for “you sent me the wrong dang thing!” They probably have me flagged as a serial returner at this point!
