Mathewkthxbai scammed me

Disclaimer: Sorry for not using any proper template - not sure how to report this one exactly.

Profile link of accused person: Mathewkthxbai

Background: I sold this guy a steam account for a 50$ wallet code which he bought from g2a. The wallet code got revoked later on and I advised him to talk to g2a support about it because they should give him a refund.
Proof the code got revoked:

He didnt like my idea and thought I wanted to scam him, he reported me here: rock superstar (admins / mods should be able to see the edit history and the original posts.) I managed to calm him down and he came to see reason that it wasn't me trying to scam him and he agreed to talk to g2a support about it. He was acting really friendly and helpful and even messaged me again 1-2 days later when g2a wanted a screenshot of steam support confirming it was this specific code that he sold me. I gave him the screenshot but never heard anything from him again.

Its been more than a week now and Mathewkthxbai hasn't replied to me anymore. Neither on discord nor on sythe.
sythe:


discord:


Furthermore he deleted all messages on discord (as you can see it looks like a monologue). Got some screenshots saved that he sent me which prove that he actually opened a ticket on g2a (he was too lazy to delete them and probably didnt think that I saved these images). I also got a screenshot which he sent me accidentally showing his real name + address. Not sure if he's aware how stupid he acts but he might know now.
Ticket opened @ g2a:



His real name/address: confident but I'll be happy to provide to any mod/admin

My suggestion: He got a refund from g2a after I gave him all the screenshots he needed but used the newly given replacement wallet code for himself because hey its free 50$ for a poor guy like him.

I'll be happy to add any more proof / screenshots, please tell me if anything is missing.

 

DNT given @Mathewkthxbai please resolve this

 

Any update to this @Mathewkthxbai & @rock superstar?

 

No he ignores me, nothing at all. Can you tell him what happens next if he doesnt reply? I'm not sure if he's aware that I'm serious and that he might be banned for this. Furthermore I'd want to give him 2-3 more days to send me a refund, maybe he can admit that he made a mistake, I dont know. He should also know that he owes me 50$ even if he gets banned and that I will most likely not just forget about it.

 

User has been banned, he can still make this right by repaying you. Let me know if he decides to @rock superstar.
