So we're all in agreement to never work for TeraNova?
As much as Kiki was at fault, you're at fault ten fold.
Yes, if Kiki had been too busy with prior work he should've turned the job down.
However in saying that, being delayed as such your response to openly slander Kiki on several websites/forums is no way to go about it.
It is highly unprofessional and just pain rude.
You should've just terminated what contract(s) you had in place and gone and found another artist, instead you've purposely gone out of your way to insult and abuse not only Kiki on multiple forums but also anyone who is in disagreement to you.
If anything you've shown your true colours to the artistic community and your name will go far and wide as a client from hell.
If anything this whole ordeal has given Kiki more exposure and support and albeit Kiki will actually get more work because of it.
You are a terrible businessman and I feel you need to go take a good hard look at yourself as a person and as a businessman and rethink your business model and professionalism.
You've dug your own grave here and as you've already seen from all the comments here and elsewhere, we all agree you're just as much (actually a lot more) in the wrong than Kiki.
Good luck with your future endeavours, hopefully you'll learn from this experience and become more mature in the way you conduct business.
Ever just woken up and gone "shit, does the world around me exist"?
