I played on the website www.bitoomba.com and I won some sum. I wanted to withdraw it, and I sent several emails with the requests to their customer services. No one replied to them. I sent more emails, but no one replied. After that I posted negative reviews on the different forums, and they finally replied. But they ripped my account and I noticed it too late. Be careful if you play on this website, because you can lose a lot. Please leave comments and share your views about this website. Thanks.
