Back in 2018 I had stumbled apon a (mainly) TF2 artist, I had initially asked her for a 2 character half body piece. She accepted and the transaction was sent (sent via Steam items equal to her prices at the time):
About 3 days later I was given a WIP piece, making me believe that the commission was soon to be done with.
After that I had sent an update ref, and a bit later she sends me saying that its done shes just on the shading now (I was not given an update photo of it 'done' asides some shading).
I (on steam) had asked her to change it to my Pyro loadout in game (hence why I asked that, but steam convos delete themselves) and just to make an icon instead of a half body. She was fine with this and proceeded to tell me that it was done and on her PC but she couldn't access it due to it being finals week and her not being allowed on her PC during them.
This was the last message I sent to her, and I have yet to hear any updates. The bit I don't have screenshots for was her telling me she'd refund me on Steam, and .. steam being the way it is. There's no way for me to retrieve those messages unfortunately. But this has been over 2 years, and she has completely ghosted me. As well as continued advertising commissions, whilst leaving mine unfinished and forgotten about.
I don't have much photo proof due to.. this being like 75% of conversations that went on.
