the documents and statements h4ns published confirm that I did not cheat him!

The documents and statements proved you promised to repay h4ns.
In the real world, to offer to give something back
is not a scam!

He asked you to refund him.
You refused.
h4ns himself confirms that I did not refuse his request!

I immediately asked him to refund my money. But his only reaction was that he closed the tickets of my pending cases which generated an automatic email notification. He's not made any further comment on this.
Closing his support tickets upon request is
confirming his request and not refusing it!

You are a scammer.
Who did I scam? How did I scam? When did the scam happen?
