Ebay customer service reps were actually really nice, but due to the system they work under were unable to help me. The issue was that I closed a return case before asking them for help with it. Apparently, if you do that you're screwed. The Ebay Money Back Guarantee is only valid if your return case is open as they can't reopen it due to "internal" policy. I actually went through the Money Back Guarantee customer policy online with the service rep on the phone and they admitted that I had a valid argument. So, if anyone higher up at Ebay reads this, please update your online customer facing documentation to be reflect what your representatives are following. Not a pleasant experience, but at least now I know. Don't close your return case for any reason until you've gotten your money back!
