Unable to withdraw

I invested 21,500 US dollars with Bervey fx As at February, I had made some considerable profits which I tried to cash, My three applications for withdrawal have been rejected and then the broker asked me to pay taxes, handling fees, etc. At first I was sceptical but I still went ahead to pay the fees after their support assured me it would be all that's required. Things went from bad to worse when the support stopped responding to my mails, they wouldn't process my withdrawal either. My investment would still be pending in Bervey fx but for Assetspoor Recovery 'Assetspoor.Tech'. I can see from other exposures that people have similar experiences with Bervey.
