They closed all my Tickets, and replied that I violated the rules of trading on MT 5 accounts) I also ask you to note that they canceled not only profit but also the initial deposit!
Even if you violate that rule, I don't think it's their rights to take your funds. Is this on their TOS?
Last time I recall most exchange (at least the reputable one) would send back the deposit money to the address where it comes from after closing the account. But this is straight-up stealing your money using a somewhat debatable offense.
