I was approached in-game by someone offering art commissions, and given that I didn't have many done of my characters and didn't have much money, I spoke with them a little bit about it.
The price was decent and so I agreed to talk about it over discord messages.
I got information from them, and provided references as well as what I was looking for, which also included the only commissioned art piece I had of the character in question.
The payment was sent, but there was some issues over how it was to be sent to them. I originally used the payment option but was told to resend it as a friend after he refunded the prior payment.
In the end, the payment issue was fixed and the agreed upon amount was received. There was a little more discussion on available times as well as an ETA on seeing the linework.
Past that point, the next time I contacted them was a little over a week later, on April 5th, to check on the progress given what they had told me about their usual turn-around times.
They messaged me a week later on the 13th that they were finished with the prior line work for a previous commission (the draenei in the screenshot) and that they were going to be starting on mine next.
Three days later on the 16th I received a message saying that we needed to discuss pricing.
I told them that we had already negotiated and agreed on the price, and that I had paid them in full and up front and that I wanted to see the line art to see if there were any changes I would like made.
There were a few things that I had an issue with and voiced them, as well as restating that I would not be paying anything further since the agreed upon price for the digital color portrait had already been paid.
They attempted to pass blame off on me for not working with them, despite during negotiations a few weeks prior on the 19th when I stated I would be more than happy to provide further assistance should they need more references or clarification from me.
They continued to attempt to re-negotiate further payment on a transaction that was already concluded and payment rendered. When I declined, and told them that I would simply take the incomplete product, they agreed. After that, they messaged me that they would probably go ahead and finish the coloring of the art piece anyway or possibly use it as practice for shading and that I should keep an eye out for it.
When I attempted to confront them on this, Discord's bot informed me my message could not be sent because I had been blocked/unfriended by them. I attempted to go to their Instagram page where they had posted the work and reply to their work. The post was rapidly deleted and my Instagram account blocked from viewing their page.
As the payment was changed from a business transaction to a gift, I know I cannot be refunded. I wouldn't have minded being out the money for this commission, but when I was told that they were essentially going to finish the drawing anyway -after- I had told them I was done, I wanted to make others aware of this artist.
