Scam/Fraud
18 Sep 2025
I was called today from this number claiming they would help me set up my trading account on their platform to which I had applied 2 weeks ago (apparently). When I told him I hadn't applied for said account, he accused me of lying. Then he asked me if I traded, and when I said that I did, he asked me whether I had made profits, and what I had invested in. When I told him I didn't want to tell him, he got irate and asked me if I didn't want to share how I was making profits. I told him that I didn't want to because I didn't even know who he was. Then he asked me what leverage I used, and when I questioned what he meant, he accused me of lying that i traded, and told me that I "didn't know shit about trading". At this point I hung up on him as he was being abusive. He claimed to be calling from Ionic Capital, and he had a mild Indian accent.
