IFC closed my account and rejected my deposit

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.
