Question.

I had this client which is buying azure account from me for $20.
And his last 2 orders got problems, And i admit it had when i checked it.
But he still complete the order with a positive feedback and tell me that he will report me on seoclerks.
I am willing to refund his last 2 orders but I have no way of doing it because he completed the order.
And now hes threatening me that he will report me.

What can i do?
