One more thing why he wanted to blackmail us is THAT HE WANTED TO GET OUR MATCHES FOR FREE AND TO RESELL, in which way, he would destroy our balance for odds for that kind of matches. He was messaging us all the time, we were answer to him very polite. He said, if we do not give him refund, we have one more chance to change our minds about giving him for free our matches that he could resell it. And again started to messaging us all the time. Very unpolite and disruptive member.
He got much bigger profit that he paid for. But he was too greedy and rude.
