Slomining 

I invested usd 3880 in SLOmining, they give me additional usd 6000 to invest on additional plan. Then I received this email:
Dear user,

Congratulations on successfully ordering the Bitcoin #5889 contract worth $5800 and enjoying an additional profit of $759.8. The system kindly reminds you that, before successfully withdrawing, you need to deposit the additional $6000 that the system has added to your account. Thank you for your understanding and support.

Best regards,
SloMining Team

Then, I wrote to support and they told me that the entire account would be frozen if I didn't deposit the additional $6,000.

Then I tried to withdraw USD 200 that was not invested and I couldn't.

SCAM!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! END OF STORY

Note:
I paid Taxes $22500. I paid the Electricity bill of $5200.
Now I paid $2000 to the customer service person Diana(Private BTC address) to withdraw my money. When I wanted to withdraw my money they put me on hold that I had to pay the Finance Department guy $ 3000(Private BTC address).
