This is a great read http://bettingresource.com/how-to-get-my-money-or-bitcoin-out-of-quadrigacx.html
Simply cancel your pending widthdrawal that has been stuck there for months and take it back to the sportsbook and use different method to withdraw the money to your bank account. After waiting over a month, I tried this and the whole process (from cancelling my pending withdrawal on qcx to money arriving in my bank account) took exactly 1 week. Lots of red flags about quadrigacx. i wouldn't feel safe having money there.
