Crown Europe Casino --i Have Enough

Hi-- i just wrote a e-mail to Crown Europe to close my account there and remove my address, and to not sending me any more mails.
they promise huge bonuses, but when you deposit you have to check well you get what they promised , and it s hard to get the missing Bonus ,they say : i will give you more % nexttime when you deposit again.etc.etc.
Once you start playing the depot melts away so quick,you want believe it , i deposited a 5-6 times with bonuses up to 250%-- but lost all fast; sometimes 200$ in 30 minutes with 50 cents a spin. Frustrating it took me so long to see what they are doing, So --think if you want a average bonus and have a chance to win sometimes, or get a fat surplus and then it goes like snow in the sun, when you play. Is there someone with similar experiences ?
