I am Sudipta Purkait, a research Scholar of Jadavpur University, Kolkata. On 13th July morning, around 8:45 am I received a phone call from an unknown number claiming his name is Deepak Verma and claiming that he is an employee of State Bank of India. H was demanding my ATM Card No for the verification of ATM Card. I believed him and he misguided and compelled me to provide him my ATM card numbers for five online purchases.
