manager extorting money

Financial manager from T-Bank. The bank offered an investment opportunity: 4₽ from us and 4₽ from you. I thought, okay, not such a big amount. They assigned a manager, everything seemed to be going according to plan. He explained everything, registered me on the platform, monitored the margin, etc. Suddenly, he said a large sum was urgently needed, there was such an opportunity, it would be great. I said I don't have that amount! And then it started... take a loan quickly! Go borrow from relatives! And they quickly switched to informal speech. Then there were threats, and some friend got involved! It was just awful what started. It all seemed official, but... of course, I felt sorry about the money and learned a lesson.
