Today, I went to deposit my cheque in hdfc akurdi branch - pune city. After depositing my cheque, bank employee asked my customer id for netbanking and my full name. After that he asked me to install the payzapp app with his referral code and pushed me to recharge my own number. I have been misguided. Also now I have fear because I have revealed my user id, mobile number and my full name. Please ensure what happened to me. Why he asked my customer id?
