They don't want to give me my money

I invested $30,000, and they tell me that I have to put in $10,000 more, to save my account, they are manipulating my account I think, because in the morning I had $40,000 in assets, now I am 18 and have a margin of 30,000 more or less, now 10,000 and This is because I told you that I no longer have money to invest, if you can help me please, I don't know what to do.

The following is the original recommendation
