I have provided my evidence in the first post. LINK OF PAYMENT.  If you check the transactions,  I sent him 147 INF first and he told me is a scam coins so he want to send it back. He couldn't resend all the 147 due to zero balance policy , so I suggested he resend 137 INF and leave 10 as balance. All can be seen from the image. Then I resend 1000 INF when we agreed on a deal.

Check the last top 3 transactions and verify my claim.
