I can understand your frustration - why is it that this kind of stuff has to happen!?! You buy a K100D Super, you should get a K100D Super - it's not rocket science!
That being said, as others have suggested, I'd just live with it - if the camera functions, then think of it as a positive - you could have bought another listing and ended up with a K100D Super that is in worse condition, has a minor irritation, didn't turn up, was missing accessories, etc etc...
AND as for HSM - non of the pancakes or limiteds have HSM, just buy them
PS, I just bought a used K100D (non-Super) and *ist D on Ebay (fingers crossed they pass all of my above checks!) and I didn't even consider the whole "super or not" issue.
Enjoy your new camera and cross that supplier off your "to be ever used again" list
