Pay attention that the conversation begins from the last picture in the post, to the first, and not the other way around.
This conversation is quite confusing to me as well. Like others, I feel that some parts of the convo are missing, and even with that, the artist treated the situation normally from the screenshots you provided, while you sounded quite threatening with your messages.
For someone that their first language isn't English, I could easily get confused by what you demanded (not from the reference picture, but actually from your message). You asked if there's going to be a male part edit for the character, which what might've confused the artist and made them think you'd like them to draw a male part for your character. (You asked them because of the preview image of the YCH, I understand, and the artist should've asked too - at same time they might've thought they knew what they're doing after that question was made.). The issue here comes from both parts. I highly doubt the artist meant to cause you harm personally by 'deciding' to change your character's parts, but rather a big misunderstanding in the language. In the end the artist provided you everything you asked without arguing or a problematic behavior, and didn't go against your wishes after. I'd consider talking to artists differently, even when mistakes are made - not jump into conclusions that the artist did such thing to personally hurt you.
