Unable to withdraw money after depositing money

Claiming to be an investment company (look at the solicitation information, the company registrant is a celebrity), sign a capital guarantee contract, and guide the registration of the jseobf.com platform (the website address is changed all the time). After making profits, the money cannot be withdrawn. They said that I didn't meet the platform standard and needed to deposit. After that, they said my password was incorrect and a margin was required again. After the margin was paid, the platform informed that the activity time had expired and a new deposit was required. During the time, investment company personnel will continue to use contracts to threaten me, telling that if I don’t deposit, I will not be compensated with high amount.
