First, I registered an account on the Jefferies Exchange. After making just one withdrawal, they started refusing further withdrawals under various pretexts, demanding all sorts of unfrozen funds and security deposits. After finally paying everything off, I could withdraw again. Now they claim my account was frozen during a third-party transfer, so I switched to cash transactions. Then they said the cash was seized by police. Since late October, they've been merging with Stonex, telling me to wait 15 business days—only to extend it another 15 days. Now I can't even log into the Stonex exchange; the link is dead. Please help me find the working link.
