"mklg" BTC chargeback attempt.

Scammer's profile link: mklg
Amount scammed: 300m (failed attempt)
Discord ID + Unique Discord ID: dude nice#9505 + 262210361573376000
Proof that it's their Discord: (See screenshots below)
Explanation of the trade: user tries to buy 07 gold through BTC. Explicitly tells me he doesn't want to wait for more than 1 blockchain confirmation because he waited "one and a hour yesterday". At this moment I know a scam is going on. I ask him to PM me his discord ID + the trading details on Sythe to link his practices to his Sythe. He then tells me he has to "take a shit first". He then tries to send me the money, I tell him I'll wait until it gets confirmed. He panics and tries to persuade me into paying anyway. I stand firm. He charges back.
How they scammed: BTC chargeback

1) Can't give the BTC tx since the transaction is not on blockchain any longer. Check screenshots: 5, 6, 8 as replacing evidence
2) Yeah: recording
