unable to withdraw

Dear , My account is 730007. The old account is 308134 of Titan markets limited. Now this company is merged with your company. I trade in MT5 and I deposit total money is 1408 $and tax of 566 $. I make profit and now total amount is 2831 $. The CS asked me to deposit tax of 566 $ while I fill withdraw form. After deposit the tax CS say you trade many times in a single day and you are using illegal software for trade and making profit. While I am using MT5 for trade. They must be have all my trading data. And now CS asking me to deposit more 500$ for inspection. CS say company will inspect your trade and data for trading many times in a single day. While this is not a rules in trading to trade limited times. They are doing cheating with me for not giving my withdrawal. I need your help to make my money withdraw.
