Scam forex broker: Unable to withdraw funds from GYD Int. Holdings LTD. (new name is ANCHGO Ltd.)

They put ads on Facebook. I inquired about it and started trading demo on their platform and was doing well following signals. I put in 5k live and lost it following their signals. Then added 10K and traded it up to 19K. Next I heard about robot trading and they gave me some info. Needed to add 20K to allow robot trading. Then I was told there was a fee of 10K to have their technical group do coding. This made me mad because I was not told about it, so I complained about it and of course was told I would make that back in a couple weeks. Now that robot trading was going well at $85K and I wanted to withdraw, they started talking about other service fees to withdraw. I told them that any service fees owed needs to come from money I made in the account or the deposit. They keep saying that it has to be paid before withdrawal. I should be able to take deposit without any fees, so I refused. Now they claim my account is frozen and assets have been confiscated by their bank. Their bank is supposedly Standard Chartered PLC per their messages. Now when I try to login to their online site, I am denied access. Also on the mt4 platform all trade history has been deleted. I have copies of all messages, transactions, trade history, etc. and will try to attach. If not, please reach out to me and I can send by email. Submitting quickly so your website will not time out again.
