Summary of scam:

• On May 10, We had set up a deal (Diamond 5 - Diamond 4 Duo Q games).
• On May 12, we played 3 games together, all which we lost. So, we decided to take a 30 minute break. When I came back from my break, he logged off.
• On May 13, I told him if it was too hard for him, he can just give me a refund and he doesn't need to worry about making up the 3 games we lost. After mentioning this, he said he can give me a refund if I want or he can continue the order.
• On May 14, when I logged on to reply, I saw that he deleted me off skype and doesn't respond to anything.

I did not receive a refund. He told me to send the money initially as friends/family, but he told me that after I sent the money via sale of goods/services (thankfully). So, I have now attempted to message him on Paypal (no luck so far). I will be escalating this case to a claim on Friday if he doesn't respond.

 

Is there anything else I need to do to prove that @ChallengerEloBooster is a scammer?

 

I have no knowledge of LoL so I have asked another mod/admin to handle this. Meanwhile he has been issued a DNT. @ChallengerEloBooster Please do not use Sythe to trade until this report has been resolved. Another moderator will get back to you asap.

 

Given that he removed you off Skype, I've banned him. Good luck with the Paypal case.
