So this person recently commissioned me to design a fursona on a base they provided. I have never taken a commission before and accepted. I colored it in and asked them what they thought, made a few edits and showed it to them. They insisted paying me $30 which I was okay with. They then said they sent the payment and I never received anything. I later found that they posted it on FA claiming they colored it themselves. I left a comment on both accounts and am now blocked on both.
