How you bought this token and where are you holding still I am not getting what is happening with you. I am not well familiar with Decentralized exchange, after you bought a token shouldn't it be at your address? So how and where they are holding your token? If they could hold your token then how the platform is Decentralized? Getting hard to understand this case. This is a fucking reason to hold tokens. My token I can and should sell at any time I want. Doesn't matter what is the current price. The decentralized system doesn't work like this. This is obvious scammy behavior.
Their token contract has a blacklist that prevents you from ever trading it. I call that a scam.
