Half of this is a lie, half is the truth.

ViaBTC does work, what I was telling him is that the odds of getting the transaction confirmed soon was low. We made an exchange:
My job was to confirm his transaction within a short period of time. His job was to pay up the 0.292 BTC. The transaction was confirmed via pushtx.btc.com, and shortly thereafter, Zaizoun went offline. A few hours after that, still without a response, Zaizoun removed me and blocked me. This is without knowing anything about how it was confirmed. This is how I know Zaizoun had no intentions of paying.

After leaving a negative for me, Zaizoun began making excuses. He tried to make up some lies about how he should not pay, etc. To get to the point, I left a negative because Zaizoun is clearly not to be trusted.

As for my side, I did my part. I confirmed the transaction, whether it cost me $10,000 to do so, or $0.01, Zaizoun was to pay me 0.292 BTC to confirm it. I did in fact use pushtx.btc.com, however Zaizoun should have no issue with this if he stuck to his word.

Since then, Zaizoun has repeatedly blocked communications with me, made up lies, and is trying to make me look like the "scammer" to try and get his red trust removed. His actions are completely untrustworthy, and although from my side I have not dealt with him in the best way, this user has been so extremely hard to deal with that I have no other options but to act aggressively in return. Until the 0.292 is repaid, the trust sticks. Making up more lies will not help. Whether I played a trick on you or not, a deal is a deal.
