Withdrawal problems. Induce you to add funds

At first, the analyst induced me to deposit $1,000 and I profited 35% within seven days. The analyst persuaded me to add funds to invest together when I second invested, $10,000 in total (I invested $3,550, the analyst invested $6,450), profiting $12,308. When I withdrew, the customer service asked me to pay 10% service fee. I let them deduct it from my account balance, but they said it can't be deducted from it. Besides, WTI asked me to pay 10% of 12,308, which is 1,230. Then I questioned them why I should pay all of it while my profit was 10% of 4,000. The company said it was none of their business. Then the USA election. The analyst hold long positions at the peak of the market, making my account balance become negative within 30 minutes. While the analyst said I owe WTI money and I have to add funds of %100,000 to get my money back. I won't trust WTI anymore since then.
