Due to Corona Lockdown many people in the country are facing financial troubles. To give some relief measures Reserve Bank of India has announced three month grace period for loan EMIs and Credit Card dues. In this time Cyber fraudsters has started to find new ways to scam the people. In some cases, fraudsters are calling customers to ask them for OTP to avail the moratorium announced by R.B.I to defer the EMIs. Once the OTP is shared by the customer, the fraudsters steal money from their account immediately. The only way to save from fraudsters is to be alert and be aware. Please remember that no bank will ask for your confidential banking details like User ID, Password, OTP, Debit/Credit Card Numbers, CVV Numbers, UPI PINs etc. to defer your EMI or interest payments.
