Is UBK Markets safe?

The UBK company promised to withdraw money from another company, which took $8,000 from me. I entered into an agreement with UBK to become their client, this gave the company the right to protect my interests. They seemed to have found the money and began making a transfer of $6,000. That’s where it all started problem. I had to pay for the stamps, because I was officially engaged in activities with them. In a word, I paid for everything. I got into huge debts (and still do) and as a result they also provided me with a payment for $500. Of course, I didn’t pay that amount I was able to. The money was never transferred to me, my personal account was blocked.
