Notrixs

Hi! I have a problem. I did play at no account casino 22/1-18 and did deposit over 45 000 swedish krons just that day. And they said i gona get 10% cashback. And i hade money left and did not get anny cash back becouse they said the did chamge owner. How do i get my money back from the last owner of noaccount casino? I have a list of my deposits at no account casino from trustly but they still say i havent deposit anny at no account casino. How do i do to fix this?
