confused and nervous---eBay strange buyer

[Xtempo]

I have in the title and all the pictures were of the slipcover of
as I put in eBay

The Sorcerer's Apprentice (BD 2010) BLU-RAY SLIPCOVER ONLY

so when the buyer recieved it well here it is.

I have never received anything Like this from E-bay, I should read real close, but YOu are going to get a Negative feedback just as soon as I can Leave it, I think You are a sorry Person and a Theif, People Like You need to be Gone from E-bay!!!!!!!!! I will try to get Hold of e-bay and see if I can get You run OFF!!!

I am not sure what to do, really and this is making me really nervous since I have never done anything but to strive to make the buyer aware of what I am selling. I have also sent a message saying what is wrong and clearly worded again that I was selling the slipcover only and what can I do to make it right.

I am already in a bad state as is it. I lost my father weeks ago but its still fresh and I am having trouble dealing with things. I am an emotional wreck and this happens. My Life sucks.
