Fell for a forex mentor who promised 10x returns in 90 days

Found this guy on Instagram showing his Lamborghini and Dubai lifestyle. He was selling a "forex mentorship" for $8,500. I paid it. The mentorship was a Telegram group where he posted signals that were wrong 70% of the time. When I asked for a refund he blocked me. I later found out the Lambo was rented and he lives with his parents.
