unable to withdraw

Hell0 I am opening this case against IFCMarkets Broker I opened a live account with this broker and funded my account via webmoney with the amount of 2000$ (13th Jan 2021 ) and I also received 600$ bonus after only 12 hours I found out that my account has been blocked and I received an email that my account has been closed because of Arbitrage !!!! the note is that I did not open any trade on my account at all !!!! the most important note in this case is that IFCMarkets blocked my whole balance and they are not allowing my to make withdrawal my Initial deposit ( 2000$ )
