My balance $6063 and I am worried about it.

My first deposit was $3000 for a good start. I made a good profit of the deposited money. And I was encouraged by their advice that to be able to have a high profit income I will double my deposit so that I could have $100,000 in 3 months of trading. They are starting to be rude. Sometimes they will not answer my emails. That’s why I decided to withdraw all the money including my profit. But the request that I sent was rejected. I sent them an email and they called me back and offered to retrieve the money for me but I have to pay 10% up front and then 10% after, of the full amount of profit that I have. I haven’t paid them anything. And now there are ignoring me.
