I don't think you can get it back mate. Bitcoin is such a currency that if you have made the transfer there is ZERO chances you can refund it. As this currency is used on most criminal and illegal stuff, I mean there is a logic reason. I learned this on businessupside.com . But anyway, I'm a investor myself, and thanks to bitcoin I manage to sustain my financial situation and afford myself a good life and for my family is very happy with it. I would not recommend you trading on it because it is very risky.
