I paid them 3000 towards an investment, but now i have no withdrawal code to retrieve my funds,

I met a man online, on occupied.com he claimed to be a pilot he told me about an investment company called abacustrade.net it was regarding crypto currency bitcoin over the course of 4 months I deposited $3000 towards an investment but I have had no return I was told I would get a car or go toawards a house, or I could withdraw my bitcoin to sell it. I don't have withdrawal code. the man Scott who claims to be a manager (only number I have is, 447418349425) says I need to give him an iTunes gift card for $100 in order to withdraw money, or get a withdrawal code. I just want my money back or for this to never happen to anyone else.
