I have a problem with a coin I purchased a while ago an hitbtc support is not solving (I written them a ticket for first time about this months ago)

They listed CRS (Starta coin) as an IOU token when they where doing the ICO. I purchased CRS in hitbtc, but they never opened the real market for this coin, and after some time they delisted the IOU. Withdrawals have been never being available either.

They last thing they asked me in support was this: "Could you please confirm if you see the workable blockchain explorer of this exact coin?" I told them that Starta Coin is based on Waves, and I gave them (again) my Waves address so they can process a manual withdrawal.

No solution till now, any idea of what can I do? I feel scammed
