Yes, I was actively using their platform but after this case, I will not process any deposits until it is resolved. I also contacted their support and I was told that the client should had broken some of the clauses from their Terms&Conditions. After I asked why the broker does not process any deposit made to that account, I was told that they are not allowed because such cases are transferred to the corresponding "government institution".
Simple check - ask them for the website and contact info of the claimed "government institution." If there is one, they'll happily provide it. If they won't provide it, there's a 99.999% chance that your case is simple theft of your money.
