Freeze my account unreasonably

Apply for withdrawal on 2021/03/21. The customer service said this was not workinhg time and their working time is 9:30-21:30 from Monday to Friday Canada Time. So I appleid for withdrawal on the morning of 3/22/2021. Then he said I repeat applying for withdrawal so my account would be frozen for abnormal situation. And my account balance in MT4 has been cleared. I have to pay 50% of my account balance to freeze my account.... This is like a scam.

The following is the original recommendation

不合理的凍結帳戶並餘額消失

我於2021/03/21在不知情的情況下跟客服申請提領新台幣客服當時告訴我目前非工作日我問了工作日是甚麼時候他告訴我是周一到週五服務時間是加拿大時間早上9:30-晚上9:30 於是我在2021/03/22的早上跟客服說明我要提領新台幣他查詢過後問我說我是不是申請過然後說我申請重複提交所以我帳戶異常被凍結說我上次的詢問就是已經申請..... 明明就是告訴我非工作日不能申請然後我要提領就用我重複申請的理由直接凍結我帳戶並且在mt4的餘額直接被消除.....然後我告訴我要我在繳納帳戶總額的百分之50才可以解凍帳戶..... 這種嚴重不合理的凍結方式根本就是向詐騙一樣....
