Summary of all this is Playbetr do not respond mails, cooperate with mediators who are their license suppliers (by license supplier this means they pay 10 000 - 15 000 a year to get a license in Curacao by a firm who operates that for them because such license in Europe is very expensive and they cant run their dirty schemes with MGA or other license providers), refuse to answer questions which I posted them here, provided 0 evidence, refused to allow me make KYC and finally decided to keep all my money and not returning deposit even thought they have that nowhere in their rules.
Also its very interesting fact that after I got scammed the numbers of complaints against them raised on many other forums and review sites.
