Submitted for withdrawal where all my trading are

Positive position. Broker call to open a few trade which I did n make some profit except for 2 counters losing in total of usd1k. Thereafter I try to log in the platform again. No such platform connections time out for all type of computer, desktop, laptop, tablet and mobile phone. Yesterday also received email that my withdrawal will be processed in 3 working subject to their fee and charges. In May 2024 loose money, I leave It status qou, only 2 days ago went in again closed all my trading I got a small profit usd365 n with my invested capital usd3400 totalling usd3700 I withdrew. Broker called said because I signed up the margin I nid trade. That goes again story of non stop trading. Now I have my lesson. But how to get the money back from them. I am a day to day selling vegetables at Malaysia small market. My hard earned money gone just like that.
