What's this?
I'm not sure I understand. Did you pay him and he claims otherwise?
Kind of a silly thing for him to do. Maybe he forgot that every transaction is recorded by these blockchains....lol
That said, you guys shouldn't actively pay for logos consisting of nothing but gradients, standard vectors and text in the first place (the touch of dropshadow needn't be mention). A modest donation would be more appropriate.
Not sure why this guy thinks he deserves some large payout, even if you did premine these coins (haven't really been paying attention so I don't know).
we're very sorry for it , because our fault , we shouldn't trust the son of bitch .
