Hence why my schedule is based on deadlines, if someone changes their deadline to a later date, then their commission will get pushed back. I can't constantly be working on one or two commissions for months because someone keeps changing their deadline. I have other deadlines too.
This person shouldn't be blacklisted because they tried to make things right and even though it took a while, the client got a full refund in the end and the commissioner learned from experience and has since then revised his guidelines. The blacklist should be kept for those who do poor work and their clients are left upset, not getting a refund or better item or down right scam people out of their money and drop off the face of the earth.
