Why didn't you refund h4ns when he asked you to do so?
I refunded h4ns
September 3rd, the same day he informed me that he does not want my further assistance!
No. You didn't.
In the real world, reducing claims from each other is refunding.

Only if both parties agree on the claim or a court intervenes.
h4ns does not owe you money. You owe h4ns money.
Pay your debts and quit whining about having a bad reputation bc you don't pay your debts.
You are not the victim.
