Luno Bitcoin trading

I was convinced to make a very small deposit and buy Bitcoin on the LUNO platform. The intermediary traded on my behalf... 3 days later he said I must pay a fee to get my profits paid into my bank account. I paid. Next day he said I first have to pay his commission of 10% before my money can be deposited. I refused. The intermediary who assisted me informed me that my profits are ready to be paid into my bank account. He also sent me a screenshot of dashboard indicating that I have R47000 in my account... He insist that I first pay a 10% commission to him before my profits can be paid to me. He blatantly refuse to pay profits.

Is this legal / normal?
