This is regarding a fraudulent transaction that happened in my account on 31st March. Some app named Volcano transferred Rs2500 in my account without my knowledge and were sending abusive messages to me n reminders stating I need to pay the amount or else they would send dirty irrelevant images to all my contacts. In a state of Panic I have made the repayment today for ₹5250. They transferred ₹2500,charged service fee of ₹2500 + ₹250 as late fee charges.I wasn't aware of this since I had not received any msg when I received that amount in my account,I only got to know it when I started receiving threat msgs to send nude pics to all my contacts. Please look into it at the earliest.
