Oh gosh, I am so sorry Missy! I can imagine how ANGRY and frustrated you must be - I would be too! What you were asking him to do was NOT unreasonable at all - after all, you DO need PROOF that the thing isn't working for pete's sake. Any "joe blow" could say that what they bought from you is defective - that way they get their money back and free goods!
Geez, some people...I swear

I hope you get this resolved soon, and in YOUR favor too!
