that is a screenshot of them asking for a 2% fee
and theres another screenshot where they say there aren't any fees
This is a classic example of a fake balance on a fake exchange (website) scam. I hope you didn't send them that 2% withdrawal fee.
If you did, there is nothing more you can do about it. You should have asked before.
Their domain was registered on 31 December 2020 and there are already scam accusations if you search with google. I don't understand why some people still fall for such schemes.
