They’re asking for 10% upfront

I’ve made a few small investments with this company over the past month without issue. After I made a larger investment and attempted to withdraw my earnings, they told me that I needed to pay a withdrawal fee of $11,118.47 to receive my money. I can’t have that amount removed from what’s being transferred, can’t cancel the withdrawal request, can’t pay a partial fee for a portion of the money, or change the amount being withdrawn. My funds are also frozen until the transfer is completed.
