I do not know if a post like this is allowed here, if not, I apologize.

This user contacted me to purchase all of my Steam gift cards. After speaking to him briefly on Skype, he removed me. He only wanted to do half/half and completely ignored me after my multiple suggestions to use ESCROW.

He also seems to be trying to provide false feedback. He linked this profile claiming it was his: View Profile: m4k - EpicNPC Marketplace

However, he already has an account there named SupremeKnifes2k17, which even viewed m4k's profile..lol

Do you have screenshots of your Skype conversation with him?

The 2 removed messages are just feedback I sent him, that I removed, after he blocked me

 

I've gone ahead and banned him on the basis that his actions are very suspicious.
