Getting money back from fraudulent seller without refund agreement

[erey_36]

Hello.
I fell for the scam described in this thread, and only realized it after sending the person money:

I'm now hoping to get my money back. But I'm stuck because of the way the resolution center is structured. I foolishly agreed to the whole thing by e-mail without any sort of legally binding document. I canceled my order, or at least tried. The seller is currently straight up refusing to refund me (via the e-mail channel), meaning that the following info I'm expected to provide to formally file a PayPal report doesn't exist:
-refund number
-agreed upon refund amount
-date at which I was supposed to get the refund

As a result, I can't finish the report because it's asking for information that I can't provide.

Update since I can't find an edit button:

In an attempt to win me back, the scammer sent me "line art", as they had promised to go that far on the advance. The comission was basically fanart for a piece of visual media, so there was no ambiguity on what the characters were supposed to look like. They managed to send me a piece that looks like someone who never saw them drew them from a verbal/written description.

This makes my situation now qualify for "product wasn't what I odered", which I can file for with info I have on hand. However, it still means the system isn't ready for people who don't get anything at all, but also don't have any formal refund agreement.

I haven't figured out how to even contact the seller.

If you click on a transaction you had with the seller in your activity, extra info appears, including means to message them. Unless you have reasons to believe that the seller isn't directly using that PayPal account (I was asked for screencaps via the e-mail channel, so it's real possibility in my case).
