Replying to Ebay Scam.

I believe I was scammed on eBay. I recently sold my camera body and got a message telling me that payment was on its way once I could verify shipping with a tracking number. I packaged up the camera sent it out and confirmed the tracking number on eBay. I haven't received payment, the buyers eBay account has been deleted and they aren't responding to any of my calls or texts. Am I fucked? Or has anyone on here been in a similar situation?

Thanks for the help NS!
