Ok, so I was ready to buy the account from him, but he also had a Bittrex account for sale and I agreed to buying both, but one at a time.
I paid for the Cryptopia, then he demanded I also pay for the Bittrex, because he could not trust me - so I am the one sending money and he cannot trust me, that sounded like ripper talk.
I told him to cancel the deal and send me back my money, that was the moment he started to ignore me.
So what to say more? Ripper after all.
(i will change/remove this post if he reply me and finish the deal properly of course).
Did op end up returning the money? If you are still owed something I would suggest compiling evidence and posting a full scam accusation thread in the appropriate section of the forum.
