Cannot withdraw on OWM. Commission unpaid.

I’ve been investing in OWM for a week and lost a lot. I did all my trade manually, but they refused to pay my commission. Later after communication, they compensated my lost principal. I want to ask, does OWM trade B market? They gave me no commission or explanation. Keep away from this kind of platform! Although the commission is not much, just a couple hundred dollars, but it is still my money. Hope you people be wise and stay away from them.
