I haven't had any issues UNTIL i started to have a really good winning streak. Wanted to withdraw some funds (not to lose it all lol) and then suddenly casino decided to hold the withdrawal for 4 days, and then they decide to close my acc. I got nothing more to say.
Sorry about your luck mate, there is no way to prove your own side of the story and we don't also know if the casinos are trying to frustrate you out of your winnings. Betspino also do not have any announcement thread in the forum and i don't think they have any representative here, so you might not be able to get your problem solved in this forum.
I am yet to visit their site and see what means of communication they offer, but let me try to go there when I have a time to spare and try to lead them here, perhaps even convince them to create an account to address the matter themselves.
Just like you, this is also the first time i am bearing of them, if they have not created any announcement thread here, i am certain they would be reluctant to come here to address this issue, OP may have to seek help somewhere else if indeed he is telling the truth.
