Tricked Into Depositing ₺6,500 on Limax Investing—Constant Pressure for a ₺350,000 Loan

I was called by someone claiming to be from investing.com, saying they work with top experts in Turkey. They convinced me to deposit ₺6,500 into their account, but after some research, I realized I had been scammed. They made it look like I earned a small amount of money, then pressured me to install Skype and Limax Investing apps. During our conversations, they kept insisting that I take out a ₺350,000 loan from the bank. I told them I no longer wanted anything to do with them and was ready to let go of the ₺6,500. However, today they called again, threatening that if I don’t log out of Limax Investing, they’ll keep charging fees through my bank. I urgently need help with this matter.
