I could not understand the trap of the scam.
I received a call from this number, and a male voice claimed he had sent me ₹2,040 and asked me to forward it to a different QR code belonging to his brother. After he sent me a text message, I transferred ₹2,000 to that QR code. Later, I realized he hadn't sent any money at all—it was a scam. No money had actually been credited to my account.
