DLCForex withdrawal issues

Hello, I requested to withdraw $50k USD from my trading account, broker came back and said that the funds were frozen due to risk control, because of my receiving money wallet address. They asked me to deposit 30% more of withdrawal money to unfreeze the money prior to sending it again and they said if I don't deposit within 10business days, my all money will be frozen forever, I will never can take it out. Can you advise what should I do? I have been contacting with customer service via Live Chat on DlcForex website listed above. My account is through DacLand Capital Limited. On their website it showed license number for Dacland capital Limited, can you please also verify their license? Thank you!
