legalbitcoinmining Broker Review

Hey Admin I really need your help. I invested $2200 in this company called Ligalbitcoinmining.com under a broker who was managing my account and later I got some funds in my account $10750 as profits but if I try to withdraw it says pending for like a week now. I tried to email them they said I need to pay $1000 for me to withdraw which I believe they still wanna scam me. I have the screenshots of my conversation with the broker and his I.G account plus the website he registered me.
