As the pm stated I have started necessary steps in pursuing the matter. I have also been advised not to respond other than stating the intentions that I plan to pursue this.

Defamation? It ain't defamation when its true. You will lose your case anyway because:
a) You do not have a legal business
b) You don't pay taxes on what you earn here
c) Hippie Tech's criticism is warranted and fair. You refused to refund him for a service you didn't deliver upon, and he followed forum protocol by opening an accusation against you.
d) You have no terms of service.
e) Neither of you signed a contract.
f) You delivered a non working executable.
g) You attempted to extort him into letting you premine his coin.
