Trade without authorization

I have knew a “friend “ in fb, she said she is doing well with trading gold so I opened the Teknos account as she guided me. She also mentioned that her best friend is a marketing director at Teknos. After several successful trades I have made a little money and she guided me to withdraw a little money as well, nothing is wrong so far. Then she said you can transfer your retirement funds or borrow from Heloc loan to put into the Teknos account and I got an email from Teknos saying that there’s a promotion for the new funds. I didn’t do that but try to withdraw the most of my funds on 9/23, but failed and the message saying “due to the maintenance of the withdraw channel, the maintenance time is 1-4 days. Then on 9/29, someone used my account to trade almost 90 times in 20 minutes and caused most of my funds lost. Who can access my account? Teknos!
