The account is frozen and only the principal is withdrawn

at first, everything i traded on the Olymp Trade platform was smooth and there were no abnormalities. However, when i applied for a withdrawal, there was a problem. The Olymp Trade platform claimed that i violated the clause that "all information provided during the account registration period and during the execution of the agreement is true and reliable" and froze my trading account. The platform said that they only refunded the my principal of USD 1,000, and the profit of USD 1,300 could not be withdrawn.
