withdrawal. reactivated account.

I funded my account last year Nov 2022 with 50 usdt ,but now after Merger Acuqustion they need us to re Activate again with 50 usdt.but they do have our money in our accounts,so to me its not fair because my account i do have funds more 15 thousands usdt ,but they another money 50 DOLLARS before 20 May 2023. I'm suspect SCAN NOW.
